Summary
• THC potency has risen roughly 10-fold since the 1970s, from 1-3% to 20-30% in flower and up to 90% in concentrates; the drug sold today is not the drug that hippies smoked at Woodstock.
• Cannabis use disorder (CUD) now affects 30% of regular users; among teenagers who use, nearly 45% meet the diagnostic criteria for substance use disorder; daily users are 5 times more likely to develop psychosis than non-users.
• Amotivational syndrome, characterized by apathy, blunted reward response, and reduced self-efficacy, is documented in the medical literature and strikes developing brains especially hard; the science is contested but the real-world damage to young people is not.
• America’s dispensary economy is a financial mess wrapped in heavy security glass: only 24% of cannabis operators reported profitability in 2023; a 280E tax code trap crushes margins; and the all-cash model makes every storefront a robbery target.
• Legalization advocates promised lower youth use, reduced crime, and tax windfalls; the evidence is mixed at best; youth cannabis use disorder rates have climbed 3.7-fold since 2015, and the federal-state legal conflict remains unresolved.
• The globalist fingerprint on marijuana promotion deserves scrutiny; the same institutional networks that gave us pharmaceutical opioids, social media addiction, and engineered food are now bankrolling the normalization of a potency-engineered intoxicant aimed squarely at America’s youth.
Introduction
I am 72 years old and have watched marijuana go from something you had to know a guy to find, to a product dispensed in brightly lit stores every few blocks in American cities. I practiced cosmetic surgery for 30 years and sat through more medical conferences than I can count, including some where the promoters of cannabis stood at the podium, visibly stoned, lecturing the audience about therapeutic potential.
This piece covers the full marijuana story, from pharmacology to politics, from the grow houses of California to the boardrooms of globalist investment funds that see a nation of distracted, apathetic, chronically intoxicated people and find it highly profitable.
What marijuana is and does
Cannabis is not precisely a sedative, although it often acts like one. Tetrahydrocannabinol (THC), the primary psychoactive compound, binds to CB1 receptors throughout the brain, particularly in the prefrontal cortex, hippocampus, basal ganglia, and cerebellum. The result is a mixed drug effect that combines euphoria, altered time perception, increased appetite, and impaired short-term memory. High doses produce anxiety, paranoia, and in some users, psychotic episodes that can persist long after the drug wears off.
Pharmacokinetics are important yet almost never discussed. THC is highly fat-soluble, meaning it distributes into the brain, liver, spleen, and adipose tissue almost immediately after inhalation. It reaches peak plasma concentration within 3-10 minutes of smoking. But the redistribution out of fat stores is slow. For infrequent users, the terminal half-life of THC in blood runs approximately 1.3 days; for frequent users, 5-13 days, because fat stores continuously release the drug back into circulation. This is not a drug that leaves your body when you feel sober. It is still there, still affecting your brain chemistry for days, and in heavy chronic users for weeks.
Urine drug testing reflects this biology. An occasional user tests positive for 3-5 days after a single session. A daily user tests positive for 30 days or longer after stopping. Hair tests detect use for up to 90 days. For workplace drug monitoring, the standard safe period of abstinence before a urine test is a minimum of 30 days for regular users, and more for those with high body fat, where the drug accumulates and releases slowly. The commonly cited figure of ‘a week or two’ dramatically underestimates detection risk for anyone who uses more than occasionally.
When ingested as edibles rather than smoked, the drug’s metabolism changes. The liver converts THC into 11-hydroxy-THC, which crosses the blood-brain barrier more readily than the parent compound and produces a stronger, longer, and less predictable effect. This is why so many naive edible users end up in emergency rooms. The dose feels like nothing for 90 minutes, then lands like a freight train.
The amotivational syndrome steals your children’s future
Smith coined the term ‘amotivational syndrome’ in 1968 to describe the diminished drive and desire to work among young, frequent cannabis users. The basic clinical picture includes apathy, passivity, difficulty initiating tasks, reduced persistence, and, as patients themselves describe, a blunted sense of caring about outcomes. The science around it is contested, but not in the way the advocates suggest.
Brain imaging studies tell the story. A 2016 study published in JAMA Psychiatry found that among young adults, escalating cannabis use produced decreasing activation of the nucleus accumbens, the brain’s primary reward center, in anticipation of financial reward. The brain stops signaling that conventional rewards, money, achievement, and recognition are worth pursuing. Cannabis becomes the reward system, crowding everything else out. This is not an abstract finding; this is the mechanism by which a generation loses its ambition.
A National Institutes of Health (NIH) longitudinal study found that cannabis use predicts lower self-efficacy across initiative, effort, and persistence, even after controlling for personality traits, demographics, and other substance use. A 2024 systematic review found that cannabis use and anhedonia, the inability to feel pleasure from normal activities, share a reciprocal relationship in adolescents: early anhedonia predisposes kids to cannabis use, and cannabis use then intensifies the anhedonia, creating a feedback loop that is genuinely difficult to escape.
The U.S. Department of Health and Human Services acknowledges the syndrome directly, warning that cannabis use in youth produces apathy, fatigue, and poor academic and work performance. Brain imaging confirms structural damage: chronic use shrinks grey matter in the hippocampus and amygdala, and alters prefrontal cortex function, the region responsible for planning, impulse control, and judgment. Adolescents are especially vulnerable because these brain regions continue to develop through the mid-20s.
The advocates argue that the science is mixed. They are right that some studies fail to find effects in adult moderate users. But moderate adult use is not what we are talking about. We are talking about teenagers using 30% THC concentrate from a vape pen daily. No study ever tested that population on those products because those products did not exist when the research was designed. The dismissal of amotivational syndrome based on studies of light adult use is like arguing that 4% beer poses no liver disease risk; therefore, 90% ethanol injections are fine.
From Woodstock weed to weapon: the potency explosion
In the 1970s, the typical joint contained 1-3% THC. Most of the product came in compressed bricks from Colombia, mixed with seeds, stems, and leaves; the actual high-THC flower made up a small fraction of what people smoked. Panama Red and Acapulco Gold were celebrated as exotic and potent. By today’s standards, they were a pharmaceutical-grade placebo.
The trajectory is documented by DEA seizure data going back to 1995, when average confiscated cannabis tested at 4% THC. By 2014, the average hit 12%. By 2018, it reached 14.88%. The current average in commercial flower runs 18-23%, with premium indoor strains regularly testing 30-35%. Concentrates, including wax, shatter, and distillates, hit 60-90%.
That is a 10-fold increase in THC dose from a single use occasion, assuming identical consumption patterns. Most users do not adjust downward to compensate. They consume the same volume and receive a qualitatively different drug experience.
The increase had two drivers. The first was the shift from outdoor landrace cultivation to controlled indoor hydroponics. Indoor growing is optimized for sinsemilla, unfertilized female flowers with extremely high THC content. Growers throughout the 1980s and 1990s discovered that eliminating seeds, precisely controlling light cycles, manipulating soil chemistry, and selecting for high-THC genetic lines produced plants that old-school Colombian farmers would not recognize. The second driver was commercialization: legal markets created economic incentives to push potency higher because customers associate high THC percentages with quality, even though the relationship between potency and therapeutic benefit is weak or nonexistent.
A 2020 University of Bath analysis synthesizing data from over 80,000 cannabis samples collected across the US, UK, Netherlands, France, Denmark, Italy, and New Zealand found that herbal cannabis THC concentrations increased by 14% between 1970 and 2017. Cannabis resin concentrations rose even faster, by 24% between 1975 and 2017. The same study found no corresponding increase in cannabidiol (CBD), the non-intoxicating compound with some legitimate therapeutic applications. The ratio of THC to CBD in seized samples shifted from 14:1 in 1995 to 80:1 in 2014. This matters because CBD modulates THC’s effects. Strip out the CBD and you strip out the natural brake on psychosis risk.
The Dutch experience is instructive. A 2018 study found that marijuana potency in the Netherlands doubled from 9% to 20% THC between 2000 and 2004. Treatment admissions for cannabis problems rose in parallel. By 2015, when potency dropped back to 15%, treatment admissions fell. Researchers estimated that each 3% increase in THC potency drives one additional person per 100,000 to seek first-time treatment for cannabis use disorder. Scale that to 44 million American monthly users, and the arithmetic is grim.
Street marijuana now commonly includes adulterants. Fentanyl, methamphetamine, phencyclidine (PCP), and synthetic cannabinoids have all been found in samples analyzed by harm-reduction laboratories. Synthetic cannabinoids, sometimes called Spice or K2, bind CB1 receptors with 10-800 times the affinity of natural THC and carry a real risk of seizure, cardiac arrest, and death. A user who thinks they are buying premium flower has no way to verify what is actually in the product without laboratory testing.
A brief history of American marijuana law
Cannabis was legal and used medicinally in the United States through the 19th century. Pharmacies stocked it. The criminalization began in earnest in 1937 with the Marihuana Tax Act, driven partly by anti-Mexican immigrant sentiment, partly by newspaper magnate William Randolph Hearst’s commercial interest in preventing hemp from competing with his timber holdings, and partly by the Federal Bureau of Narcotics under Harry Anslinger, who made cannabis prohibition a career project.
The Controlled Substances Act of 1970 classified cannabis as a Schedule I drug alongside heroin, defined as having high abuse potential and no accepted medical use. This classification has never been seriously revised despite decades of contradictory evidence. Richard Nixon ignored his own commission’s 1972 recommendation to decriminalize personal use. His domestic policy chief, John Ehrlichman, later admitted the War on Drugs was designed partly to criminalize Black Americans and the anti-war left, not to address genuine public health concerns.
Oregon became the first state to decriminalize simple possession in 1973. Alaska, California, Colorado, Maine, and Ohio followed in 1975. The Reagan years reversed much of this, re-criminalizing possession in most states by 1983. The current legalization wave began in 1996, when California voters passed Proposition 215, legalizing medical cannabis. Colorado and Washington made history on November 6, 2012, becoming the first states to legalize recreational adult use through ballot initiatives. Colorado began retail sales on January 1, 2014. As of 2025, 24 states and the District of Columbia have legalized recreational adult use, and 37 states have legal medical programs.
Federal law has not moved. Cannabis is still Schedule I. The state-federal conflict produces absurd results: a dispensary owner operating fully in compliance with California law can be federally prosecuted for trafficking. Federal employees and contractors tested for drugs can lose their jobs for using cannabis legally under their state’s law. Military service members are automatically disqualified. The Cole Memorandum of 2013, under which the Obama administration agreed not to prioritize federal enforcement in states with functional regulatory schemes, was rescinded by Jeff Sessions in 2018, then effectively reinstated under political pressure. The Trump administration issued an executive order in December 2025 directing the Justice Department to expedite rescheduling cannabis from Schedule I to Schedule III, which would not legalize it but would remove the punishing 280E tax restriction.
People are still in prison for marijuana. The racial disparity in enforcement is well-documented. Among those federally sentenced for marijuana trafficking in 2024, 34.5% were Hispanic, 32% were Black, and 24.4% were White, despite roughly equal use rates across racial groups. Some states still carry multi-decade mandatory minimums for possession with intent to distribute. The national reckoning with these sentences has been slow and incomplete.
The dispensary economy: glamorous on the outside, chaos underneath
Marijuana dispensaries now outnumber Starbucks in many American cities. The business model looks simple: buy wholesale, sell retail, collect taxes. The reality is considerably more complicated.
The core problem is banking. Because cannabis is federally illegal, most traditional banks will not service dispensaries. Federal Deposit Insurance Corporation (FDIC) insurance and federal anti-money-laundering laws create liability that most financial institutions are unwilling to accept. The result is that the vast majority of dispensaries operate as cash-only businesses, handling hundreds of thousands of dollars in small bills per week, in buildings full of a highly desirable and portable commodity.
This creates the security theater that any visitor to a dispensary notices: the heavy exterior gates, the vestibule airlock entry, the uniformed guards, the bulletproof glass between staff and customers, and the cameras in every corner. Industry budgets for security run $100,000-150,000 annually per location, covering guards, surveillance systems, and armored-car cash transport. Washington state dispensaries reported 67 armed robberies in the first months of 2022 alone, roughly double the prior year’s pace. One large Colorado dispensary chain suffered 15 break-ins during 2020. Los Angeles data shows dispensary theft nearly doubled between 2021 and 2022.
The financial picture is sobering. Average established adult-use dispensaries generate $1.8-2.2 million in annual revenue. Gross margins on flowers run 15-25%; accessories hit 50-70%. But the Internal Revenue Code’s Section 280E, written in 1982 for cocaine dealers and never updated for the legal cannabis industry, prohibits any business that traffics in Schedule I substances from deducting ordinary business expenses such as rent, payroll, marketing, and utilities. A dispensary with $2 million in revenue and $300,000 net income before taxes can face an effective federal tax rate exceeding 70%. Many operations that look profitable on a revenue basis are unprofitable after 280E. MJBizDaily found that only 57% of standalone dispensaries were profitable in 2022. A Whitney Economics study found that only 24.4% of cannabis operators across the US reported profitability in 2023, down from 42% in 2022.
The black market never went away. Legal cannabis prices, burdened by licensing fees, compliance costs, and 280E, are typically higher than street prices. California’s illicit cannabis market is estimated to be 2-3 times the size of its legal market. In some jurisdictions, dispensaries obtain inventory from unlicensed growers to stay price-competitive. The seed-to-sale tracking systems meant to prevent this are imperfect. The promise that legalization would eliminate black market cannabis has not materialized.
Some dispensaries appear designed primarily for money laundering. They sit on corner lots in depressed neighborhoods, show few customers, maintain minimal staff, and generate suspicious uniformity in their reported sales figures. No one has systematically investigated this, and given the all-cash business model, no one is particularly motivated to look.
The growers’ and import situation
Legal cannabis cultivation operates in every state with a recreational or medical program. California’s Central Valley and Humboldt County region produce enormous volumes. Colorado, Washington, and Oregon have mature commercial markets. Indoor operations in former warehouse districts of major cities are now common.
The illegal domestic growing industry also thrives. National forests in California, Oregon, and Washington have been sites of large cartel-operated outdoor grows, sometimes employing workers in conditions approaching labor trafficking. These operations use heavy pesticide applications, illegally divert water from streams, and leave toxic residues in the environment. Law enforcement seizures document the annual destruction of millions of plants from illegal grow sites, making no apparent dent in supply.
Legal cannabis is not supposed to cross state lines, even between two legal states, because interstate commerce of a Schedule I substance violates federal law. This prohibition is widely violated and rarely enforced at the individual consumer level. At the wholesale level, sophisticated operators have found ways to move product across state lines under the cover of legal hemp transport, since hemp and cannabis are visually identical and hemp is federally legal.
Cannabis imports from Mexico, which once dominated the US market, have declined as domestic production increased. Mexican cartels have shifted their US operations toward fentanyl and methamphetamine, which are more profitable per pound. However, Mexican-grown cannabis still enters the market through border state smuggling channels and is typically lower-quality, lower-potency product sold at the bottom of the market.
Pesticide contamination in commercial cannabis is a genuine hazard. Cannabis plants are potent accumulators of whatever they are grown in, a property called phytoaccumulation. Regulated legal grows still show pesticide contamination in testing, because the regulatory frameworks for cannabis agriculture lag decades behind those for food crops. Illegal grows use whatever chemicals keep pests away without concern for residue levels. A 2020 study of California dispensary products found pesticide residues in a significant fraction of tested samples.
Combustion of any plant material produces polycyclic aromatic hydrocarbons (PAHs), carbon monoxide, and respiratory irritants. Cannabis smoke contains many of the same toxic combustion products as tobacco smoke, though without nicotine. Regular cannabis smokers show increased rates of chronic bronchitis and respiratory symptoms. Unlike tobacco, the association with lung cancer is less clearly established, possibly because tobacco smokers typically smoke 10-20 cigarettes per day while cannabis smokers use much less total plant material. Vaping concentrates avoids combustion products but delivers massive THC doses with its own risk profile.
Sativa, indica, and the pharmacology of the high
Cannabis sativa and Cannabis indica are the two major species, with most commercial products being hybrids of both. The distinction matters to consumers and dispensary staff, though the science behind the marketing is somewhat thinner than advertised.
The traditional description holds that sativa strains produce an energizing, cerebral, creative high, while indica strains produce body relaxation, sedation, and the couch-lock phenomenon. The reality is more complicated: the effects depend more on the specific cannabinoid and terpene profile of the individual strain than on its species classification. Many strains labeled sativa at one dispensary are labeled indica at another.
For sleep, high-myrcene indica-dominant strains with moderate THC and elevated CBD have the most supporting evidence. CBD has anxiolytic and sedating properties without the intoxicating effects of THC, and its absence from most high-potency commercial products is precisely why those products are less useful for genuine medical purposes. For anxiety, the picture is paradoxical: low doses of THC can reduce anxiety while high doses reliably produce it; this is one reason that the explosion of 30% THC products is counterproductive for the medical claims the industry makes.
Synthetic THC exists as well. Two FDA-approved medications, Marinol (dronabinol), which contains synthetic delta-9-THC, and Syndros, a liquid version, are approved for anorexia in HIV/AIDS patients and chemotherapy-induced nausea. Cesamet (nabilone), a synthetic cannabinoid analog, is approved for the same purposes. These synthetic formulations allow standardized dosing, which is the fundamental problem with smoked or vaped cannabis for medical purposes: no one reliably knows the dose they are receiving. Whether synthetic THC is safer or more dangerous than plant-derived cannabis for health purposes has not been definitively studied; the mechanisms of action are similar but the full chemical context is different.
How addictive is it?
The claim that marijuana is not addictive is false. Cannabis use disorder (CUD) is a recognized psychiatric diagnosis in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), defined as continued cannabis use despite clinically significant impairment. The DSM-5 also recognizes a cannabis withdrawal syndrome: dysphoria, anxiety, irritability, insomnia, decreased appetite, and restlessness that typically begin within the first week of abstinence and resolve over 1-3 weeks.
By the numbers: approximately 30% of all cannabis users develop CUD at some point. Among those who use daily or near-daily, 17-19% develop dependence. In 2024, nearly 7% of all US teens and adults met the diagnostic criteria for CUD; among those aged 18-25, the rate was nearly 16%. Among teenagers ages 12-17 who use cannabis, 45.2% meet criteria for a substance use disorder. The American Academy of Pediatrics calls this a public health emergency.
The comparison to other drugs is instructive. Roughly 9% of tobacco users become dependent, 15% of alcohol users, 23% of heroin users, and 30% of cannabis users. Cannabis is more addictive than tobacco by this measure. The common cultural framing, that weed is harmless and non-addictive while tobacco is dangerous, does not survive contact with the data.
Daily cannabis users are 5 times more likely to develop psychosis than non-users. The association between high-potency cannabis and psychosis is particularly strong: users of 30%-plus THC products show dramatically elevated psychosis risk compared to users of lower-potency products. A 2019 European multicenter study published in The Lancet found that use of high-potency cannabis products was associated with 5 times the risk of psychotic disorder compared to non-use. In cities where the most potent strains dominated the market, such as Amsterdam and London, the investigators attributed nearly half of the new psychosis cases to cannabis use.
Total US cannabis use has surged. In 2024, 44.3 million Americans used cannabis monthly. Cannabis use rates among adults now exceed tobacco use rates for the first time in American history. Rates of substance use disorder involving marijuana are 3.7 times higher in 2024 than in 2015. This is not a stable situation; it is an accelerating one.
Children are the most important issue
Everything described above is worse for adolescents. Their brains are still developing. The prefrontal cortex, responsible for impulse control, planning, and judgment, does not fully mature until the mid-20s. THC disrupts the pruning and myelination processes that occur during adolescence, with lasting consequences for cognitive function.
Adolescents ages 13-18 who use cannabis are more than twice as likely to develop mild or moderate depression and more than 3 times as likely to develop major depressive disorder compared to non-using peers. More frequent use in this age group links to increased odds of suicide attempts and greater severity of depressive episodes. Regular adolescent cannabis use that begins before age 15 is associated with IQ drops averaging 8 points that persist into adulthood.
Comment: This is half a standard deviation, a huge effect.
Roughly 4,200 individuals ages 12-20 try cannabis for the first time every day in the United States. Nearly 5% of adolescents report first use before age 13. These are not abstract statistics. These are children whose brains are being altered during the developmental window that determines the cognitive and emotional equipment they will carry for the rest of their lives.
When I was in medical school, it was understood that certain interventions during critical developmental periods produce irreversible changes. We knew this about thalidomide, about alcohol, about ionizing radiation. We know about THC, too, or we should. The difference is that no one is making money off the others anymore.
Does legalization help or hurt: what the natural experiments show
The advocates promised that legalization would lower youth use by moving cannabis out of the unregulated black market; reduce crime by eliminating drug arrests and defunding cartels; generate tax revenue for schools and public services; and allow sensible regulation of a product people were using anyway.
The reality is mixed. Tax revenues are real: legalization states collectively generated $4.4 billion in cannabis tax revenue from adult-use sales in 2024 alone. Crime associated with cannabis arrests has dropped in legal states. Some data suggest that property crime drops modestly in areas where dispensaries open, possibly because occupied and monitored storefronts reduce the appeal of vacant-lot drug dealing.
Youth use is the central question, and the evidence does not support the optimistic projections. The Monitoring the Future survey, which has tracked youth substance use for decades, has not shown the legalization-reduces-teen-use effect the advocates predicted. Teen marijuana use disorder rates have increased substantially in the years following state-level legalization, though isolating causation from correlation is methodologically difficult.
Portugal decriminalized all drug use in 2001, treating possession as a public health matter rather than a criminal one and investing the savings in treatment. Drug-related deaths and HIV transmission among intravenous users fell dramatically. Use rates stayed roughly flat or declined modestly. This is often cited as proof that decriminalization works, and by some measures it does: the criminal justice harms of prohibition are real. But Portugal’s approach was decriminalization combined with aggressive investment in treatment, not commercialization and promotion. The American experiment is different.
Singapore sits at the other end of the spectrum. Possession of more than 500 grams of cannabis is a mandatory death sentence. Singapore has among the lowest drug use rates of any country in the world. The social cost in civil liberties is extreme. This is not a model any Western democracy would adopt, but it is a clean data point: draconian enforcement does reduce use, at enormous human cost.
The most useful domestic comparison is between US states. A 2018 study found that violent crime dropped 13% on average in states near those that had legalized medical marijuana, attributed partly to cartel revenue reduction. Studies comparing early-adopter recreational states like Colorado and Washington to comparable non-legalizing states have found modest increases in adult cannabis use, roughly flat or slightly increased teen use, some evidence of increased cannabis-impaired driving, and no clear evidence of increased use of other drugs. The picture is genuinely complicated, and anyone who tells you it is all positive or all negative is selling something.
Globalist fingerprints
I have documented in prior posts the pattern by which globalist-aligned institutions promote policies that weaken national cohesion, lower fertility, and reduce the capacity to resist centralized control. The cannabis normalization campaign fits this pattern with precision.
Follow the money. The venture capital and private equity firms that bankrolled commercial cannabis legalization include some of the same institutional investors heavily involved in pharmaceutical opioids, social media platforms engineered to maximize addictive engagement, and processed food companies that optimize for palatability over nutrition. The goal is not to give people a recreational option; the goal is to create large, captive, dependent customer populations whose political engagement is low and whose critical faculties are chemically suppressed.
The academic and media apparatus around cannabis promotion deserves the same scrutiny I have given pharmaceutical-funded research. Organizations that advocate for cannabis policy change receive funding from cannabis industry interests. Researchers who present at cannabis-related medical conferences are often financially tied to cannabis businesses. I have sat in those conference rooms and watched speakers deliver word salad about endocannabinoid system optimization while manifestly struggling to form complete sentences. These are not disinterested scientists; they were high.
The specific targeting of youth is not accidental. High-potency vape products in candy flavors, gummy edibles in children’s packaging, social media marketing that reaches teenagers, dispensary storefronts in neighborhoods with high concentrations of young people: these are the choices of an industry that knows its most valuable customers are those who develop dependence early and maintain it for decades. The tobacco industry ran the same playbook.
The apathy that high-THC cannabis produces in regular users is not a side effect. For the psychopaths running these institutions, it is the product. An apathetic population does not vote, does not organize, does not resist. The collapse of civic participation among heavy cannabis users is not a coincidence; it is a feature.
Once we fell for pharmaceutical opioids, the perpetrators faced minimal consequences and moved on to the next campaign. Cannabis normalization follows the same template: capture the regulatory agencies, fund the academic advocates, control the media narrative, mock the skeptics as reactionaries, and collect the revenue while the damage accumulates in the population.
Humans are remarkably durable.
We have been absorbing mercury from dental amalgams for 150 years, and most of us have not dropped dead. We were jabbed with COVID vaccine bioweapons, and millions survived. We have endured healthcare systems that kill more people than they save. We adapt, compensate, and carry on.
Many people use cannabis regularly and function at high levels. The people most severely harmed are the young, the genetically predisposed, the already mentally ill, and the heavy users of high-potency concentrates. The casual adult who uses a low-potency edible occasionally for sleep is probably not heading toward psychosis or motivational collapse. This caveat is not a defense of the industry; it is an acknowledgment that individual outcomes vary.
The lesson from human resilience is not that the assault does not matter. It is that even when we are being deliberately poisoned, we fight back at the cellular and social levels. Parents notice something wrong with their children and stop it. Clinicians document the harm and publish it. Skeptics read it and push back. The system wants us to be passive and overwhelmed. Refusing to be either is the appropriate response.
Synthesis
The marijuana story is not primarily pharmacology. It is about what happens when a society allows commercial interests to define the acceptable level of harm for a product that alters brain chemistry, with special targeting of the developmental years when that alteration is most damaging and most permanent.
The 10-fold increase in THC potency between 1970 and today was not inevitable. It was the result of market incentives operating without regulatory constraint, the same dynamic that gave us opioid tablets of escalating strength marketed as safer alternatives to street heroin. We know how that ended.
The clinical evidence on adolescent cannabis damage is not ambiguous. The brain imaging data, the longitudinal studies, and the population-level data on depression, psychosis, and cognitive decline in early users are consistent. The argument that science is too mixed to act on is the same argument the tobacco industry deployed for 40 years. We should not need another generation of destroyed children to settle the question.
Legalization, done properly, is probably better than the current state of affairs: it reduces racially discriminatory enforcement, generates tax revenue, and enables some quality control. But legalization as currently practiced, with 30% THC flowers and 90% concentrate vapes sold with candy branding in stores near high schools, is not harm reduction. It is commercialization with a public health theater.
The population that most needs protecting from this drug is the one with the least political power to demand it: children and adolescents. Their interests are not represented by cannabis industry lobbyists, state tax revenue projections, or academic researchers with industry ties. The adults who should be protecting them are instead debating whether amotivational syndrome is sufficiently documented to warrant concern, while dispensaries open across the street from middle schools.
The globalist institutions that benefit from a passive, apathetic, chronically impaired population are not going to police themselves. The parents and clinicians who see the damage accumulating before them will have to do it. This means demanding potency caps. This means keeping commercial cannabis out of neighborhoods with high concentrations of young people. This means treating youth cannabis use disorder as the medical emergency it is, not a lifestyle choice to be tolerated. The drug warriors were wrong about many things, but they were right that protecting developing brains from powerful intoxicants is a legitimate public health goal. We threw that out along with the excesses, and we are paying for it now.

Ever since he smoked a blunt on Joe Rogan’s show people have assumed that smoking pot is what gave Elon Musk the entrepreneurial drive to become the world’s richest man. But people forget that Elon also dropped a lot of acid, consumed magic mushrooms, cocaine, MDMA, ayahuasca and ketamine. What happened to Elon cannot all be attributed to pot.
Musk was made by the CIA. Like Bezos, Zuckerberg, and people like Winston Churchill and Chump for that matter, the CIA/Establishment made them, they’re hardly the come-from-the-middle-class types that they’re billed as. Quite the opposite in fact. A short dive into their pasts is all it takes.
Kids should stick to cigarettes and alcohol and not to high thc potency marijuana? Preferably no use to any of the 3.

Reefer Madness. Good grief.
It is reefer madness in Colorado for sure. Or the drug zombie apocalypse. Iu2019m over it.
Really? I live in Colorado. What about us is “reefer madness”?
For starters, employees of the judiciary showing up high as a kite to work, not having read cases and thus failing at oneu2019s job. People administering medications to elderly at u201Ccare homesu201D or caring for special needs children. Or my personal favorite, a mother of a 30 year old Druvet Syndrome woman who used edible marijuana so much that she ended up in a hospital for psychiatric reasons, thus abandoning her child. She moved here from Ohio for weed. Then there is the issue of more traffic accidents as well as a domestic violence system that was overtaken by people who moved here without jobs and fabricate DV so they can overtake what few shelters Colorado had since the regular homeless shelters are full. . I have seen it all firsthand. I loathe what Colorado has become since legalizing marijuana. I donu2019t use it and I resent having to smell it out in the open.
Are they showing up at their jobs that way? Why is it being tolerated? It’s not tolerated in alcohol use. Why blame the plant rather than the humans who are misbehaving?
My impression regarding the shelters is that fentanyl is the big culprit there, plus the fact that homelessness has become big business, esp in blue states. Homeless people come to blue states for the generous handouts.
And I am happy that our prisons are no longer full of pot users and sellers. Tolerating a whiff of pot in the open seems the far lesser evil. And organized crime cannot use pot to stuff its pockets (though I hear that some illegal farms remain, to supply other states that still haven’t ditched their prohibition).
Another thing Colorado did well, was to set the regulations so that communities can opt out. Gunnison, for example, remains dispensary free. That’s a sensible policy.
Sorry, too busy fighting/navigating the drug zombie apocalypse to respond. Meth, fentanyl, heroin, weed, and who knows what else. As well as navigating all the literal human crap on the streets. Have a lovely day.
Boy, Denver must have gone the way of San Franisco since I was there last. What a shame.
Funny movie.
Not saying Cannabis is good for people, but Reefer Madness is one hysterically funny PSA. Right up there with The Room in movies that are so bad they’re good.
I wonu2019t disagree with the points you have raised in this essay but you have failed to mention many aspects which have value: cannabis is very helpful to those with spasticity and muscle tension, nothing works better with fewer side effects. You mention the effect of additives such as fertilisers and sprayed on fentanyl etc and yet these are not quantified and are very relevant to the scientific analysis. You conflate the problems of smoking (burning) along with vaping and yet these two consumption methods are very different. Many of the people who have problems perceived to be caused by cannabis use already had mental illness problems and were looking to self medicate. In short, this is an interesting essay but woefully biased especially referencing the American market.
I suggest you go find a podcast or Youtube about how China has taken over the Marijuana growing trade in Maine and what the Chinese liberally spray all over the plants, fully unmonitored and unregulated. Things have changed. Its Russian roulette, and the wrong cocktail has life-altering consequences. God requires us to value the gift of life in every way. We dont poison our lungs with burning plants or take unnecessary risks.
I appreciate that cannabis is being grown and sold in an unhealthy way but that doesnu2019t mean the plant itself should be demonised. Itu2019s very easy to grow in the garden and so you know the provenance. The audience for Robertu2019s Substack is multi national so confining it to a discussion of what happens in the American market and then extrapolate that to cannabis generally is as I said, biased.
If you can find seeds? They are carefully controlled.
I have seen many ads for seeds from Canada. But it takes skill to grow from seed. When you say sale of seeds is carefully controlled, what do you mean?
In Colorado, small plants that are cloned female, are available for purchase in some dispensaries. And for those who are concerned about how cannabis is grown, there are many dispensaries that sell what they grow, and will show you. Cannabis is an amazingly sturdy, hardy plant, insects and diseases rarely bother it outdoors, all it needs is water.
I havenu2019t smoked weed since I was a teen in the 70u2019s-80u2019s. Back then you could buy a lid for $10 and it had tons of seeds. I am a gardener I think it would be fun to grow. I grew it high school and it was easy. My husband has smoked weed for decades. He hasnu2019t found seeds in his weed since it became legal. So that is what I mean about it being controlled.
Oh so you mean quality control? That makes sense, most people don’t want to pay for seeds.
Isn’t it amazing how much one plant produces? The old Marin County pot growers had a gold mine.
STH, cannabis is called weed because it grows so easily! You just need to make sure itu2019s organically grown so you donu2019t have chemicals in the bud. Growing from seed is simple and nearly always works and the reason you donu2019t find seeds anymore is because the seeds you buy now are feminised so they donu2019t produce seeds unless you have a male plant – thatu2019s where the control comes in because you definitely donu2019t want a male plant as it doesnu2019t produce the bud which is the strongest part of the plant. If youu2019ve grown tomatoes from seed then you can grow cannabis.
Yup! I grew tons when I was a 15
Thank you for this.
Itu2019s true. I see the vape oils with 80-90% THC and am disgusted that the U.S. has allowed this to happen. I took one hit off a vape pen and hallucinated and had a migraine the rest of the night. I have tried the dispensary weed and if Iu2019m sober for months and take few hits, I start throwing up within the hour. Something is wrong with that stuff, and I donu2019t trust the people selling it to tell me if itu2019s laced with pesticides and fungicides.
Also, nearly three years ago, our daughter arrived to visit us in full psychosis after using a high concentrate THC pen. She spent a week in a psychiatric hospital followed by months of therapy. Sheu2019s still not the same. She is still drawn to it.
Iu2019m not a prude, but I am very careful about what goes into my body. Iu2019m not going to trust the same people who pushed opioids on us to tell me itu2019s safe.
Thank you for sharing your experiences. Quite telling.
yeah, and who knows if those vape oils are polluted with something worse than just pesticides and fungicides – like maybe even with fentanyl (or other devious drugs), as Dr Y mentioned.
When the vape oils first came on the market, we know a woman in her 40s who lost her legs below the knees because of the Vitamin E Acetate they were then using as a preservative in the oils. If they were not smart enough to know what damage that would do to users when inhaled, why would they be any smarter about other chemicals they are using today?
Oklahoma, ironically, was infiltrated by Chinese cartels and the state has a hazardous waste mess to clean up when they left town, all while operating under the nose of local law enforcement.
wow, so sorry to hear about all this mayhem with yourself, your daughter and the other woman. i guess maybe it comes down to “when in doubt, don’t”. but i get it that everyone is so stressed and dysregulated these days that naturally we are all looking for something to help us cope. i think a big factor is the totally unregulated (and govt, media and big-telecom-driven) wireless radiation everywhere, including very close-range devices like cellphones & wifi.
Crack cocaine w hunter biden and Charlie sheen is another alternative?
My daughter also went into schizophrenia after taking up the habit and full blown panic attacks and still has mental disturbances 30 years later. Is it worth the risk of life long ruin? no
Uh huh, had to be that, no other possible reason(s). Case closed. Go have a Budweiser to celebrate noodling that out.
I discovered by accident that THC is a bronchodilator. Some athletes use it pre workout to boost their endurance. It probably saved a vacation we took to hike in CO as a family member couldn’t comfortably breathe due to the altitude and nearly had panic attacks. Next day we took 1/2 2.5 edibles and were hiking like the locals with minimal (or no high). The only situation I would advocate using it… for me. I don’t like the feeling and the new strains are so unpredictable I refuse to drop $60-100 for an experiment that’s likely going to fail. Marijuana anonymous is a fairly new thing and growing! Pharma ultimately gets another pay out as they probably get those addicted on some form of antipsychotic to “treat” their dependency.
On your last point, thats exactly how the rehab centers work, and it becomes a wicked cycle for addicts in and out of rehab clinics until all their resources, or more often, their family’s are drained.
Oh I know from experience! It’s a wicked system. I pushed back hard and hopefully was part of the reason the medical director was fired.
Yes, it’s been shown to counter the effects of tobacco use. Best is 15-20% THC which can be calculated with a formula
Thank you, Dr. Yoho, for this deep dive into the history behind cannabis!
When I first opened it, I thought I would just skim over a little bit and move on to the next email. As I started, it became so intriguing and interesting that I couldnu2019t move on!
Iu2019m over 54 years in recovery and hadnu2019t realized how dangerous the simple pot that I smoked in my teens had become. Now I know how and why it is damaging our youth.
I will be passing this along to my children, who donu2019t use drugs, for the benefit of my grandchildren. I hope and pray that anyone else who reads this does the same!
My ex-husband is 73 and has been smoking pot since he was 14 yrs old. He worked very hard and never showed any side effects of his pot smoking but on the other hand, it was not easy, nor fun, to live with this. I think some people are wired differently and pot does not affect them in the same way as most others. He always remained focused and full of energy and ambition, etc. I smoked at that time, long ago now, and wanted to stop as it did affect me and I could not function well on it. I quit and never smoked it again. I am against it, as it is something all people use to alter their reality. That alone signifies immaturity and lack of ability to make good decisions for your life. I see these old users as very immature in many ways. They do not grow and mature like people should. That alone is why I hate the USE of marijuana on the scale it is used today. I see nothing good about any of it. The only use I see is when someone uses it to control nausea when they are very ill and from side effects of life saving drugs.
Usually the only people who advocate or like pot are the ones using it. They LOVE it. They never see the pitfalls and don’t care about growth and maturity being halted. Thus, addiction is real.
I’m sure it’s like other things, if you’re using it every single day, it’s best to take a look at yourself. If you use it irregularly it’s an entirely different matter. I have orthopedic pain, and when I REALLY need a good night’s sleep, I’ll have some and sleep like a baby.
YES, A NEED FOR USING IT THERAPUETICALLY IS ENTIRELY DIFFERENT. It is not then abuse of a substance. My neighbor’s son has cystic fibrosis and is on life saving drugs but they make him not able to eat as much as he should so he smokes a little pot which gives him an appetite. But most pot users are just getting high, as we all know.
Oh noes.
Oh wow!!! Thank you for that deep and knowledgeable response.
Well fantastic… but what about the 1.65 billion other humans who didn’t experience uD83EuDD14 ex husbands fortunate ways.

I am against drug use if not necessary for health or pain issues. Just sharing my experience and what I have found to be true regarding pot smoking. The world is in a bad place and using drugs will never help.
Ty!!! well said well put!!
What about CBD oil … the full or broad spectrum ones. I see several cancer protocols (including Joe Tippens original protocol) that use CBD oil, so just curious. Thanks.
harmless
Thank you for the reply.
A lot of CBD will have a small amount of THC.
Clear, concise and informative.
We are truly fortunate to have a few conscious and truthful scientists on our side.
Your information is useful and welcome to consider. I correct not the content, but references at the beginning.
Pot was not specifically a hippie thing. It was simply readily available in many places, as you say yourself. At the university of 40,000 students I attended during the “hippie” period in the late ’60’s, marijuana use was so prevalent and accepted that the school newspaper’s front page headline announced, “Grass Prices Are Up….”
Also, Woodstock is protrayed now, decades later, as a hippie event. It was a music fest. Period. Yes, some stereotypical hippie-looking people are featured in film records of it.
I was wondering if the reuteri yogurt would help you and now you mention it at the end of your post! I made it a few years ago but saw a video with Dr Davis that got me interested in making it again. Amazon is delivering the ingredients today so I can make it and have some by tomorrow. I also got Akkermansia because of Mercolau2019s new book and Iu2019m considering fermenting it too.
I ferment the three species I’m most deficient in
We do instapot X36 hours with Fairlife whole milk & Lactobacillus Reuteri (1 capsule sprinkled in).
Dr. Tamara Santa Anau2019s a gem!
u2764uFE0FuD83DuDE4F
As far as I can tell, this was her original idea.
Would love to hear you interview her about fermenting L Reuteri!
Dr Davis does mention Parkinsonu2019s as well as many other benefits in some of his videos.
Thank you for letting us in on your journey to healing! u2764uFE0FuD83DuDE4CuD83CuDFFCuD83DuDCAA
Excellent article.
Here in north Florida we were right in the middle of all the wild west sort of doings that were the marijuana trade in the 1960s, 70s and up to today.
There was great camaraderie among smugglers, growers and users, which I would now list as another part of the addictive nature, social validation.
“Best friends” from the past would no longer speak to me once I quit growing weed, getting high, and smuggling in the early1980s.
This was also about the time the cocaine guys showed up in force and these were not laid back hippie types like everyone in the weed scene. They were cold blooded killers intent on capturing the market over a pile of dead bodies.
The reasons I quit getting high were that I was building my first scrap metal business and it was glaringly obvious I was screwing up by having my decision making severely impaired by smoking weed.
The second motivator was the draconian confiscation laws put in place about the same time. Get caught with weed and they could automatically take everything you owned.
I didn’t want to lose my property and business assets.
Not to mention doing time.
I had quit growing just in time.
Within the next year the black helicopters with infrared scanners showed up and a whole lot of growers were busted.
Learning now that so much of the counterculture was fabricated by the feds to stop the anti war movement makes me thankful I quit when I did without having life long consequences.
I would never go back to doing drugs if only for the reason mentioned here that they were a tool to fill the prisons with the people the system didn’t like.
“they were a tool to fill the prisons with the people the system didn’t like.”
They sure were. That’s drug war for ya.
All of these hyped scare stories. Not so scary for those of us around in the 70’s. Reefer Madness is still showing. People demand anu laws be set for those scary exceptions and it it were the rule.
How many quibblers lined up for their warp speed clot shots? Essentially ALL of the Physicians and researchers and experts and their “studies” CLAMOURED over their “professional” resources said “safe and effective”.
Here’s one: This just in from more “experts”: MJ is Baaaaad…VERY bad, you didn’t know this because you are not wearing a while lab coat with a god complex…
It should be illegal to sell it. If you want to smoke it grow your own. Share it but not for any compensation.
That’s kind of how things are regarding alcohol. In my state, you can set up your own still and brew your own moonshine. Drink it, share it, give bottles away. But no selling.
An interesting point.
That’s like it is in many places with magic mushrooms too nowadays. The guides just give them away.
You do not mention how Cannabis oil with high THC has been shown to cure cancers. This does not create the “high” if given via suppository.
Supply references.
Look up Dr. Robert Melamede. There are several doctors in Israel who have verified this.
Dr. Ethan Russo is also a prestigious scientist involved with Cannabis. I found the book: The Survivor’s Guide to Medical Cannabis by Regina Nelson, PhD
I read the above book and it was quite interesting.
I think she is referring to RSO, aka Rick Simpson Oil, taken by the back door method. He has 2 books (poorly written, but he was not an author, so good on him for making this info public). There was also a documentary, pre-Covid times, following a woman with brain cancer. She was taking RSO but at the last minute caved to traditional treatment which in the end killed her (surprise). Apparently, when they checked for the cancer, not sure at what stage, it was already gone. Sorry, I canu2019t remember much more but this might still be found online. They sell RSO by syringe for the protocol in Canada (online) for about $1200 CAD.
I have read his book and watched his video. They are both very informative.
A number of years ago a 7 year old had lymphoma in her chest. Chemo did not touch it. However RSO cured her and quickly.
Wow. Thatu2019s amazing.
https://www.cannabisscience.com/
Here’s the references
Good essay, and yes the current scene is a nationwide disaster. The addictiveness of the modern stuff is clear. The old 4 – 8% stuff was an entirely different beast – “Poems, Prayers and Promises” by John Denver covers it pretty well. There was more CBD in those also, with the synergy enabling a lot of precious bonding and easy laughter, rarely seen today.
The saddest part I think is the loss of its tremendous medical potential including massive benefits to conditions ranging from cancer to PTSD to Parkinson’s. In right dosage, the increase in interoception and insight alone is powerful. Unfortunately, that dose has morphed from a couple (shared) tokes to the impossible 1/4 toke – and as you point out, that is only if one is lucky enough to find a strain not infinitely hybridized and chemicalized into poison.
I would add that we are also in extreme societal times where sacred plant medicines, used wisely, can still open up one’s awareness to more agentic, holistic, transformational, and Earth-honoring possibilities than the online A I control grid being implemented by rich warmongering covid-foisting pedophiles at the wheel. Am I being paranoid? Naive? I still do think that even a few “stolen” moments of freedom remain priceless.
Having said this, everything you have written is true. And this makes it all a very ugly, complex situation demanding great care.
Where I end up is looking to other transformational technologies as more primary sources of self-unfoldment: ceremony, spirituality, shadow work circles, yoga, breathwork, meditation, nature immersions, hard work, fitness, empathic relationships, etc. The underlying need for self-actualization, for journeying, for transcendence (for literally being able to imagine a future at all!) should not be overlooked in the conversation. Finding strategies to meet this primal human need more directly with less cost – especially for youth whose souls are being neglected in so many ways – offers a healing path forward.
Thank you for this important essay.
lovely note
When we were pitched the legalization of marijuana in CA, I was thinking it would be the stuff from the 80s and 90s. Those that pushed for the legalization must have known it was already lethal. As Dr. Yoho writes, follow the money. I know kids whose futures were derailed by doing weed in high school. Schizophrenic episodes are real. A young guy who should be at Yale is going to community college because of his mental instability. Luckily, my kid, like me, didn’t like weed because it caused anxiety. At our local dog park, young guys think nothing of vaping/smoking in the morning. Can you imagine if someone were popping open a beer that early?
Do not take the hemp derived Delta 9 or similar it is far worse, even a small amount at bedtime. As an adult, I have used THC over the years for sleep but couldn’t get it in the state I moved to so obtained Delta 9. It metabolizes differently. I took about 2.5 mg at 9pm, went to sleep but was still “high” (all of the symptoms that people hate feeling high get) for more than 24 hours. I suspect that even if a large nan took a whole 10 mg. Delta 9 gummy, he would be mostly incapacitated,,, dangerous driving etc.
I really appreciate how thorough and objective this article appears to be. It makes clear that cannabis effects are complicated and that outcomes are a mixed bag. I want people to be fully informed of all the health risks of cannabis, and this is very helpful.
I cringe however at the notion that generating more tax revenue is a benefit. Someone’s not paying attention to how badly governments spend our money, which includes the, as noted, highly destructive restrictions that force dispensaries to transact in cash.
Let’s keep government out wherever possible, save for restrictions on sales to minors, enacted at the local level. Let’s keep doing research, keep expanding knowledge and awareness, and expose the exploiters for what they are: dirty rats who are quite happy to do great damage to young lives.
Above all, keep preaching to friends who use to keep their dosages DOWN! People are amazingly ignorant when it comes to dosage, especially when using for the first time, or for the first time in a long time (e.g., after they leave a job or career that does drug testing).
This is exactly right!! Watched as my brother over time using Marijuana deteriorated! All the psychosis was present. One day I found him DEAD!
A deep sadness will always be with me. He was 12 years younger & now DEAD! Donu2019t Fu2026.,king use it or CBD! And do Not give it to your pet!!
Thank you for alerting people!
My friend’s 15 year old son took a heavy dose and developed immediate and full blown epilepsy… He’ll never drive and is a constant source of nagging anxiety for her.
The cloying sweet stench of that plant evoked in me a visceral revulsion the first time I smelt it in the pages of a book I’d borrowed. I did try some oil to help heal a wound 10 years ago, to no avail. The weed and I just don’t resonate.
“Cannabis use disorder (CUD) now affects 30% of regular users; among teenagers who use, nearly 45% meet the diagnostic criteria for substance use disorder; daily users are 5 times more likely to develop psychosis than non-users.”
Haha. Now do alcohol, Robert.
Thanks for your comment. The alcohol post is already written, and it’s in a lineup waiting to be dropped.
uFEFFI appreciate this article and the research behind it. Thanks doc. However, one also needs to look at the benefits of the plant itself, outside of the industry skulduggery.
I am in Canada, where cannabis is legal, right or wrong, there it is. The perps credited with making cannabis criminal – Carnigie, Anslinger, Rockefeller and the like were hell bent on besmirching its name in order to ring in the age of pharma. Apparently, these perps took one of Godu2019s herbs that was used medicinally (as you mentioned), ruined its name, gave it a new name, u201Cmarijuanau201D (racist against Mexicans) and cleared out the competition for their new pharma products. The war against hippies was also in full swing.
One or more of them had a hand in that ridiculous fear porn movie, later called u201CReefer Madnessu201D, in order to dupe the public into thinking cannabis would cause you to murder your neighbour. And we all know how influential TVs can be. As you say, always about the money.
While cannabis may have some issues with the newer high THC strains and the developing brains of the young, its biggest side effect, in my experience, is a wild case of the giggles and wondering where the chips are. Of course, responsible folks would only partake after a long day when the potential of couch-lock would not be an issue. Nothing wrong with sleeping on a cloud either. Much better than popping sleeping pills. And as for being lazy, absolutely not if used properly, i.e., not for breakfast.
Who did those studies saying cannabis was harmful? The NIH was mentioned. Maybe it was Fauci? uD83EuDDD0 Are we trusting anything that came out of there? Ditto for all the other mainstream agencies. What were their interests? Who paid for the studies? If they are saying this is bad, then Iu2019m filling up my vape with fresh herb and pressing on. (Not those nasty e-vapes, a real vape, easy on the lungs.) Iu2019ve also read that real tobacco, not with the additives in cigarettes, is also a miracle plant. I can see the same pattern here.
And what about those with cancer, when an appetite would be a miracle? What about the work of Rick Simpson (RSO) at curing cancer? He claimed the medicine was in the THC. Of course, used as a suppository, the TCH provided no high, which worked well for many. He also witnessed some with schizophrenia become well, while taking the herb. Did anyone study that, I wonder? If it was not that great, why did they run him out of Canada when he offered his cure, perhaps naively, to the cancer board?
So much skullduggery behind a medicinal herb, all at the hands of a perverted generation. Iu2019m not buying it. There are those who grow cannabis organically in their yards, completely legal in Canada and elsewhere, to take the edge off of their anxiety in the evening. I also find CBD to be a miracle indeed. Fresh herb, juiced, has been known to be excellent for Crohnu2019s and colitis.
It may have some problems, if any of these studies are real and true, but its benefits cannot be denied. I once read that one would have to consume 1500 lbs of cannabis at once in order for it to kill them. Compare that to iatrogenic deaths and itu2019s looking quite good. A good giggle or two is well-needed these days anyway. uD83DuDE09
The only way to kill someone with pot is to drop a bale of it from the roof on their head. Alcohol? Drink a smallish bottle of strong liquor all at once, and chances are huge you’ll drop dead on the spot.
That’s a great comment and I appreciate it, but we have many medicinal options. And my opinion remains after doing all this work that the hazards and problems of cannabis outweigh the benefits. But again, thank you for the effort you put into your response, and it’s another point of view.
The biotech company cannabis science has been using cannabis to cure cancer for years now. It also promotes neurogenesis, which is the creation of new brain cells. After smoking it for 20 years, mensa told me my IQ was in the 96th percentile. It also promotes apoptosis which is how it cures cancer. Indoor growing doesn’t increase the level of thc at all, selective breeding does.
We have thc receptors so our metabolism does use it for certain purposes. If your body doesn’t need it anymore you stop reaching for it. It’s not physically addictive and it was even announced on the radio in 1975 in the usa that it cures cancer. Growing your own is the safest way. You have certainly not researched this very well and seem to be quoting only govt sources. It’s like you’ve been programmed to avoid lots of research on cannabis. I’d suggest you go to the cannabis science website and look at their success in curing the worst kinds of cancer. Rick Simpson in cannabis who was an ex chemist and then a farmer, cured his whole town in Canada with it. There’s a documentary on it which documents the research you’ve failed to find. It’s also been known since the 70s that it’s good for epileptics. I used to have epilepsy. Sorry Robert, but this article is a load of bollocks because it is missing so many sources like you’ve been pushed to miss the research on benefits. Looks like you’ve been captured by the government to promote that it causes harm to stop people finding out the huge health benefits.Cannabis is also not physically addictive compound. Cannabis indica makes you sleepy, while sativa makes you talkative and energetic as you say.
Wherever you got your information, you’ve been fooled into missing the huge body of research that proves its benefits.
It’s best to grow yourself so you don’t have to use pesticides and can grow it organically without water contaminated with aluminium. You certainly haven’t researched this well at all. Cannabis has also been shown to. The Dsm5 says a lot of things which are false. Cannabis users get use disorder because of the type of people they are, not because of cannabis use. Cannabis is proven to cause a lot of healing, especially cancer. In 1975 it was announced it cures cancer by govt scientists. Rick Simpson cured his whole town of cannabis. It’s great for nausea too. Grow. Your own and your safe.
Promoting neurogenesis and apoptosis is a good thing. I had to smoke it every day for years due to chronic health issues which have now resolved and I no longer reach for it during the day. It is far safer and causes less social problems than alcohol as it doesn’t cause violence like alcohol does.
There is no evidence it’s physically addictive. It looks like you’ve been had.
Mark is my friend, so I will refrain from rebutting his viewpoint.
And you are mine of course
Mark saved my wife’s life.
And it was a pleasure to do so, and built up my treasures in heaven a little bit more I’m sure.
Robert, I am betting 10 bucks against a potato you couldn”t, rebut anything Mark says about pot, given that you believe what you wrote above.
But it’s nice to see you hold no grudges. 🙂
I don’t have to rebut anything he says. It’s already been rebutted by scientific research, and what an absolutely ridiculous comment you’ve made
What? I was talking to Robert. I’ll go amend my comment. Sorry for the confusion, your stuff is right on.
I don’t care who you wrote the comment to. There is something very wrong with your thought processes. I am a good friend of Roberts and the disease his wife suffered from would very likely not have been reversed without my knowledge and coaching
Robert can write anything he wants. He is also entitled to change his mind about things in the future, but that gives you no reason to treat him with such disrespect.
Mark, I have no disrespect for Robert. If a piece of writing is terrible, I do say so sometimes. If I care enough. Here, I do.
I follow the ad hominem fallacy advice: attack the argument, not the person. Can you see the difference?
Erin, the biotech company curingsome of the worst kind of cancers is http://www.cannabisscience.com
I appreciate the link, Mark. Will check them out.
No problem Erin
No problem erin
Where did Erin ever say he could not? Nowhere. For some reason, people seem to love to inject something never said to change the subject to have a conversation with themselves.
It seems you’re a bit confused about what ad hominem means. Perhaps you should actually find out the definition of ad hominem as Erin got it back to front, and you fell for it hook line and sinker, without checking.
Ad hominem, short for argumentum ad hominem, refers to several types of arguments where the speaker attacks the character, motive, or some other attribute of the person making an argument rather than the substance of the argument itself.
So ad hominem doesn’t mean you are attacking the argument, it means you are attacking the person.
Looks like you need to do something about increasing your IQ so you aren’t so gullible
More ad hominems. Another dimension on why your resident friend here won’t bother commenting. Have a great day.
You led an ad hominem attack against me when you were totally wrong, so I thought I’d return the favour
Erin also attacked Robert(not the argument) by suggesting he has priors he isn’t mentioning. Do you see now how you’ve made a fool of yourself because you failed to fact check and read all Erin’s comments. Opening yourself up to ridicule with your lack of understanding is not a good look
Right. Ask questions and get the shart-snark. Another apparent dimension of why the host won’t bother.
You have shown yourself to be gullible, and do you think Robert spends all day liking or replying to comments? Due to the huge number of articles he’s written, I suspect he spends most of his time writing Your mistaken comments were directed at me not Robert, so why on earth do you think he would reply to things you said to me?
Time to smarten up dude
yet you say nothing when I scientifically debunk your whole article.
Mark, I am guessing Robert has priors he is not telling us about. Sad. But he is a sharp guy and so there is hope for him.. 🙂
Thanks for the cancer info. Do you have a really good link on that?
You are guessing? That’s pretty foolish and defamatory. There is certainly no hope for you. I’ve already provided the link you’ve requested. Perhaps you should just read it
Both CBD by itself and thc has also been demonstrated to stop the shakes of Parkinson’s and as it promotes the creation of new brain cells is very beneficial for Parkinson’s patients all over the world. I think you actually need to check the veracity of your sources instead of just believing theyust be true. Cannabis use also eats into the profits of the pharmaceutical industry
Well, I have a pot brownie at bedtime and I’m going to carry on doing that!
This is a shocking hatchet job, Robert, damaging trust in other things you evaluate. You dwell on the negatives; there is no section of your article that lists the positives which have been heavily documented, from being an effective anti-emetic for cancer patients for whom the usual ondansetron pills et al quit working, to neuropathic pain, to anti-epilepsy, all the way to sleep aids. A whole book could be written about the good effects.
You rehash the argument from the 80s drug warriors — omg, the stuff is stronger! Well, if it’s stronger, you need less of it. Which is good news for the users, esp. if they smoke it. Always has been. It needs care in its use — of course it does. But it will never poison you or kill you like alcohol, which needs a lot more care in its use.
That said, I am against any use by kids. Alcohol, tobacco, pot, or pharma pills.
Edit: All the more shocking since there seems to be visual documentation that pot helps substantially in Parkinson’s tremors. Interested? Look it up on YT.
You are so correct!
Thanks for your comment, Erin. I don’t find it convincing, but I appreciate the effort you’ve taken, and of course, I’ve seen those Parkinson’s improvements on YouTube, and I have tried smoking pot, and it doesn’t work for me. Best and wait for what I do to alcohol in a few weeks.
Your argumentation sucks, Robert. That is my overall point. Pot is stronger? People use less. Stays in the body for a bit? So does ginseng, valerian, echinacea and St John’s Wort. So what? Dispensaries next to schools? Not in Colorado. Triggers psychosis? So does alcohol. So do many forms of stress. And so on and so on.
You have nothing. Just a rehash of the old drug warrior nonsense. And apparently no interest to engage on the substance.
Sorry to hear it does not help the tremors in your case.
Thanks for being here and I appreciate what you have to say despite disagreeing.
https://www.cannabisscience.com/
here’s the website of the biotech company curing cancer with cannabis
it hasn’t lowered my IQ, caused psychosis or addiction. Funnily enough it was found I was autodidactic the year I started smoking it. it’s not physically addictive. certain personalities cause overuse disorder not cannabis. I’ve never witnessed any bad effects and regular use stops you getting high. there’s videos of people stopping Parkinson’s shakes with CBD alone which is anti-psychotic
You do repeat yourself often in your responses. AI?
It’s because there has been a lot of problems with the oppo substack app this morning, which has posted comments before I’ve finished them and I’m unable to find them to edit them. I couldn’t even reply to your assumption on the substack app. I had to use the web version to do so.
Assuming things which aren’t real isn’t a good look. Perhaps in future you should question the reasons for things more thoroughly, instead of jumping to conclusions
I brain biopsied Mark and he has a native IQ in excess of 150. So, he could lose a quarter of it and he’d still be fine.
Thank you very much RobertuD83DuDC4D
This is what AI tells me this morning about Colorado youth use:
“Youth cannabis use in Colorado has declined since legalization, contradicting earlier prohibitionist fears that it would increase. Past-30-day use among high schoolers fell from 19.7% in 2013 (just before retail shops opened in 2014) to 12.8% in 2023, representing a drop of nearly 7 percentage points.
While some state data from 2020 indicated that overall use “has not significantly changed” compared to pre-legalization levels depending on the specific timeframe analyzed, the most recent trends show a substantial decrease. The Colorado Department of Public Health and Environment reports that youth use is now lower than the national average and significantly lower than the rates observed in 2009 (24.8%) and 2013 (19.7%).”
Edit: And I can attest that the Colorado market, after experiencing its gold fever days, has substantially declined. Many shops closed. People who really want it or need it medicinally grow their own — its ridiculously undemanding to cultivate outdoors.
Sounds hopeful.
I once spent some time working with a CPA who had figured out how to keep records to beat Section 280E, shifting the various costs into COGS, Cost of Goods Sold. Wrote a book on it, not exactly a best-seller. This required an intensive amount of recordkeeping on the part of the outlet, and monitoring on the accountantu2019s side. It worked, his clients kept more profits than others. All cash. He tried to have me service a client, but when I saw the work involved, I declined. Everything had to be perfect or the IRS could have a field day. He charged outrageous fees and nobody complained. Havenu2019t talked to him in a while, he thought Federal rules might make this gift horse go away by normalizing things. He was Jewish and didnu2019t smoke, btw.
I survived the 70’s just fine, thank you, and retired well, but don’t recommend it for anybody starting out their path in life. I got lucky.
MARIJUANA IS A DEMON uD83DuDC7F
Youu2019re a misinformation spreader itu2019s not called CUD you lost all credibility with your jargon pumped garbage of throwing spaghetti at the wall and regurgitating bits of what you hear incorrectly. Your just someone trying to sell things
Be respectful. We are all doing our best here.
I don’t think you are, doing your best in this. And I am very sorry to see this, being a long time fan of yours.
I think you have priors you have not disclosed. Normally, you are so cogent. This screed is not normal.
Has anyone looked at cold processed CBD? Soaked in 50/50 alcohol/coconut oil it produces no THC without being heated. Without THC are there still harms?
It seems harmless to me from what I’ve read, but my focus was on THC.
I suppose there could still be the contamination issue. And there are some of sensations like the munchies and other mild weirdness. But nothing major that I have noticed.
As we have come to anticipate this treatise is comprehensive and covers most issues.
Weed is mostly an alternative to alcohol arguably the better choice.
Hybridization is responsible for the huge increase in % THC . Users choose varieties for specific reasons. Indicus strains are useful for muscle relaxation or sleep assistance.
Sativa strains are motivating but also facilitate creativity.
Most strains are hybrids. Knowing the parents of the cross determine effects.
Knowing how much to ingest, like any drug requires knowledge.
Harvard trained MD Andrew Weil studied many psycho active plants in indiginous use for centuries around the planet.
The conclusion was that refining is associated with addiction and the societal woes like theft and violent crime. Unrefined substances did not have these issues.
Those conclusions were prior to the widespread breeding and cloning that are now
the entire weed market.
The fact that dispensaries grift for the state is hardly surprising. Consumers want access and choice. That is exactly what they have. Growers are not profitable because the state has become the recipient of the $$$. A strong case can be made it was far better before.
Addictive personalities unsurprisingly addict. Substance has mostly to do with availability.
Weed is still superior to other narcotics mostly in pill form.
As mentioned the “strains” commonly sold have THC % that make them dangerous.
Knowledge and useage constraints are not difficult to manage for most users.
Gummies are candy with THC. Not a great choice.
Weed smokers unlike alcohol impaired typically do not kill others in automobiles.
Long term usage was not associated with psychosis in years past. The current strains have created a serious problem due to potency.
The human body has cannabinoid receptors, they did not develop them to receive THC from weed.
THANKS Rob foe this reminder! It is incredible that such an OLD plant which gave humanity food, clothing, fuel and so much more, is being used to, according to this title, turn people well, into idiots.. I’m not familiar with the details of temperature influence on the THC level, but that alone is totally scary:

I bet you knew this would be a controversial post, Dr. Yoho!
My only wish is that the advocates could try to make their case without using alcohol to validate their argument. It removes their credibility. That reasoning made it very easyy to shut down the potheads in my town when they came begging for a cannibas dispensary. From firsthand experience, a pot smoker’s critical thinking skills and ability to persuade is noticeably dulled. Let’s not tell them though. 😉
You need every bit of your brain these days to survive. And I agree with your viewpoint above.
Thank you, Dr.! I enjoy the wide range of topics you cover on your stack.
It is a massive amount of work.
Great article. It breaks my heart reading about the different ways we are being poisoned and sabotaged.
While there may be some merit in some of the author’s comments, I have to strongly disagree with the premise that marijuana is bad. I have interviewed nearly 500 people on my Cannabis Health Radio podcast and many of those people were given only months to live primarily with a serious cancer diagnosis. In nearly 30 interviews with people who had brain tumors they all used cannabis and all but two of them are alive today. They didn’t smoke cannabis or vape or consumed edibles. they used cannabis oil either orally or by suppository to avoid the psychoactive effect. To date, there have been 57,000 studies of cannabis. It’s easy to cherry pick a study to support one’s argument but to condemn a plant that has been used for thousands of years for health benefits is, to me, disingenuous.
I greatly appreciate the praise that I’ve gotten for this episode and the time my readers have taken to comment, even the negative ones. I wasn’t sure it would resonate, but as you see, the vast majority of comments are positive.
After working on this thing and reading about all these problems over and over, I have resolved not to let any of this stuff into my body ever again. It’s just too dangerous; it’s filled with pesticides and sometimes adulterants, the quality is uneven, and it’s just too damn strong.u00A0We have thousands of therapeutic herbs and medications, and I just can’t see spending any time with one that has all these side effects.
My alcohol post is already written and I will drop it within a couple of weeks.
well done Dr. Yoho. and afaic, a real public service.
Thank you, Y!
Hope you did your own research and thinking this time.
Alcohol is easy. It is truly addictive, not habit forming like weed
It kills people, causes cancer, weed doesn’t – 6 million a year dead from alcohol.
It kills brains cells, weed create brain cells
Men attack their wives when drinking.
Men attack the fridge when smoking weed.
Weed helps you sleep and it indicated as treatment for over 20 different physiological conditions.
Alcohol ? Every blackout is a measurable neurotoxic event. Hippocampal encoding shuts down. That is why blackout memories do not form u2014 not because you forgot them, but because the hippocampus was too chemically suppressed to encode them in the first place. The cells were not doing their job because the toxin load was too high.
Chronic alcohol use produces documented hippocampal volume reduction, white matter degradation, Wernicke-Korsakoff syndrome from thiamine depletion, and cerebellar atrophy. All structural. All measurable on imaging. All progressive with continued use.
Where is your head at, trying to equate weed with that?
Seriously irrational prejudice
Canu2019t it just be weed is not good for you, neither is alcohol.
Right. So much conversation here on why it’s better than alcohol. The two drugs could hardly be more different. Yes, alcohol can have incredibly bad effects, not limited to blackouts, violence, dangerous driving, fetal alcohol syndrome, a destroyed life/family and cirrhosis of the liver.
Cannabis is more subtle, at least in the beginning. But many people of my generation started smoking it in the sixties and never stopped. It is a daily habit for lots of folks; some use it several times a day. I have seen lives detrimentally altered by its chronic addictive use. Amotivational syndrome (lack of motivation) is a real and serious effect. It is difficult for some so-affected to pursue a career or even hold a job. Plus there are adverse health effects, some of which are not well known.
Anything can harm you. Even water in excess can kill. That some people use pot badly is no argument against an herb that can be so healing.
true Erin. i am not saying pot has no upsides. in fact i copied some of the cannabis cancer-cure info to save. my point was to counter the drumbeat of “booze is so much worse than pot” here, when in fact the two substances have almost nothing in common other than their ability to alter the mind (which they also do in wildly divergent ways). and you’re right. anything can be abused, or used responsibly.
Thank you for explaining that. The reason we talk about alcohol is that it’s a useful comparison for people who don’t understand toxicity of various substances. I figure that since we humans have learned to navigate a substance like alcohol, we can surely learn it with cannabis.
Good to hear back from you!
total bullshit. typical of the < average I.Q.. person, they think whatever prejudiced opinion they have in their brain, must be true. I smoke it every day. 40 plus years. I have an IQ in the top 3% of the population, with a POI, or pattern recognition in the top 1%. Tested by pros. I am 63 years old, can do 160 pushups in 5 minutes, hang from a bar for 2 minutes 30 seconds. I am a licensed legal professional., have a trade license, and write meta research in my spare time. Nope, your ignorance is not fact. It is total bullshit. Claude rips you a new one, based on the evidence of fact I found to debunk Yohou2019s bullshit.. "The two drugs could hardly be more different." Correct. They couldn't. One is a confirmed neurotoxin that suppresses hippocampal function at recreational doses, causes structural brain damage with chronic use, and kills approximately 95,000 people per year in the US alone. Marijuana activates the CB1u2192ERKu2192BDNFu2192neurogenesis chain. (That means brain cell creation, proven in science) Yantra accidentally made our argument. "Alcohol can have incredibly bad effects u2014 blackouts, violence, dangerous driving, fetal alcohol syndrome, destroyed life/family, cirrhosis." Also correct. Every item on that list is a documented neurotoxic or systemic toxic outcome. Fetal alcohol syndrome is permanent, irreversible, structural brain damage in a developing human. It is the leading preventable cause of intellectual disability in the Western world. Yoho never mentions it. Yantra mentions it and then pivots to cannabis anyway. "Cannabis is more subtle, at least in the beginning." This is the tell. "At least in the beginning" implies escalating harm over time. No mechanistic basis is offered. No citation. It is an impression dressed as an observation. "Many people of my generation started smoking it in the sixties and never stopped." Anecdote. Not evidence. Survivorship bias cuts both ways u2014 those same people also lived through leaded gasoline, widespread pesticide use, unregulated food additives, and the beginning of municipal fluoridation. Attributing their outcomes to cannabis requires controlling for everything else. Yantra does not. Nor does Yoho. "Amotivational syndrome is a real and serious effect." Amotivational syndrome as a discrete cannabis-caused clinical entity has been contested in the literature for decades. The primary studies supporting it fail to control for pre-existing depression, socioeconomic stress, and u2014 critically u2014 the same neurotoxic confounder stack we have documented throughout this rebuttal. What is documented: chronic heavy cannabis use in individuals with pre-existing low dopaminergic tone may reduce motivation. What is not documented: that cannabis causes amotivational syndrome as a universal or even common outcome in adult users. The Canadian Government Commission (1972) documented the opposite phenomenology u2014 enhanced energy, creativity, and interpersonal engagement u2014 in typical adult users. Furthermore: alcohol-induced anhedonia and motivational collapse following chronic use is extensively documented, neurobiologically explained by dopaminergic downregulation, and orders of magnitude more prevalent in the clinical population. Yantra does not mention it. "I have seen lives detrimentally altered by its chronic addictive use." Clinical observation without confounders is anecdote. People whose lives are detrimentally altered by heavy daily cannabis use typically present with pre-existing anxiety, trauma histories, socioeconomic instability, and concurrent alcohol or other substance use. Isolating cannabis as the causal variable from a clinical observation is not methodology. It is pattern-matching under confirmation bias. "There are adverse health effects, some of which are not well known." This is a content-free statement. Every substance has adverse health effects. Water has adverse health effects at sufficient dose. The relevant questions are: what are the effects, at what dose, in what population, compared to what baseline, controlling for what confounders. Yantra answers none of these. META-LEVEL: Yantra correctly identifies that alcohol and cannabis are very different drugs, lists alcohol's documented harms accurately, and then pivots to cannabis concern without applying the same evidentiary standard to either substance. The comment is a demonstration of the asymmetric scrutiny the rebuttal documents throughout. Cannabis gets clinical suspicion. Alcohol gets a list of harms and a shrug. That is not analysis. That is cultural bias with a medical vocabulary attached.u201D Claude
Alcohol too has its benefits. It just needs to be used with care.
Sure I use it to make my tinctures and clean my wounds. Doesnu2019t change the fact it is a brain damaging killer when used for an addiction.. Look everyone gets their choice. Want to help yourself into dementia? Drink a case of beer a day. Your call. I donu2019t care. But I do not stand for anyone feeding bullshit in order to front their own prejudice.
Alcohol cleans the veins of plaque… and the French are said to overcome the effects of their rich sauces by a glass or two of wine every day. A little alcohol before bed boosts GABA and helps sleep. And alcohol can be a nice mood boost and social lubricant. I avoid black and white thinking wherever I can.
Wrong again. You boozers sure like to frost over the harm huh 😛 I think your phrase should have been ” I avoid thinking about uncomfortable truths”.
“”Alcohol cleans the veins of plaque”
This is the resveratrol argument in disguise. The claim originates from observational studies showing lower cardiovascular mortality in moderate drinkers. The mechanism proposed was HDL elevation and mild anticoagulation.
What the literature actually shows: the resveratrol content in a glass of wine is pharmacologically trivial. You would need hundreds of glasses to approach therapeutic resveratrol doses. The cardiovascular “benefit” in observational studies is now largely attributed to the sick quitter effect u2014 heavy drinkers and sick people stop drinking, making abstainers look unhealthy by comparison. Mendelian randomization studies, which control for this, show no cardiovascular benefit from alcohol at any dose.
The American Heart Association, the WHO, and the NTP all currently state there is no safe level of alcohol consumption for cancer risk. The “cleans veins” claim is a 1990s finding that did not survive methodological scrutiny.
==============
“The French paradox”
The French paradox u2014 high saturated fat diet, low cardiovascular disease u2014 has been attributed to wine consumption since Serge Renaud’s 1991 work. It has since been explained by: underreporting of French cardiovascular deaths, Mediterranean dietary patterns, lower ultra-processed food consumption, and smaller portion sizes. Wine is not the variable. It was never isolated as the variable. The French paradox as an argument for alcohol benefit has been largely abandoned in the cardiology literature.
=======================
“A little alcohol before bed boosts GABA and helps sleep”
Mechanistically half-true and functionally false.
Alcohol does potentiate GABA-A receptors u2014 that is why it produces sedation. It does help people fall asleep faster. That is where the benefit ends.
Alcohol suppresses REM sleep. REM is when memory consolidation, emotional processing, and neural repair occur. Alcohol-induced sleep is neurologically non-restorative. Users fall asleep faster and wake feeling unrefreshed because the sleep architecture is disrupted throughout the night as blood alcohol drops and the rebound effect kicks in. The rebound u2014 glutamate surge as GABA suppression lifts u2014 causes fragmented sleep in the second half of the night.
Chronic use as a sleep aid produces tolerance, dependence, and progressive sleep architecture degradation. This is not sleep medicine. It is CNS depression being mistaken for rest. (It also damages your brain.)
====================
“Alcohol can be a nice mood boost and social lubricant”
Accurate description of acute effect. Not a health claim. Cocaine is also a mood boost and social lubricant. The acute phenomenological experience of a substance is not evidence of its safety profile.
( I dont need a social lubricant: while I don’t recommend brain damage, or cancer or liver issues in order to feel comfortable around people.. )
The mood boost is dopaminergic and GABAergic disinhibition. It is real. It is also followed by a corresponding rebound u2014 the well-documented “hangxiety” effect u2014 as neurochemistry corrects. Chronic use downregulates the dopamine system, producing anhedonia and baseline anxiety that require increasing doses to temporarily resolve. That is the addiction mechanism.
(And it doesn’t erase the cancer, the dementia, the dead brain cells…)
============================
“I avoid black and white thinking wherever I can”
This is deployed as a sophistication signal u2014 implying that anyone who questions alcohol’s benefits is being reductive. It is a rhetorical move, not an argument. The claim that alcohol has some benefits does not neutralize the mechanistic evidence of its toxicity. Nuance requires acknowledging both. Erin acknowledges the benefits and waves at the harms without engaging them.
===================
ABOUT NOD’S COMMENT:
“”Solid.
“Want to help yourself into dementia? ”
Drinking alcohol MODERATELY is associated with measurable hippocampal volume reduction. Topiwala et al. (2017, BMJ) showed no safe threshold for hippocampal atrophy. Even moderate drinkers showed greater hippocampal shrinkage than abstainers. Accurate neurotoxicity framing.
“I do not stand for anyone feeding bullshit in order to front their own prejudice”
u2014 that is the methodological position of the entire rebuttal stated in one sentence.””
===================
META-LEVEL:
Erin is doing what the rebuttal documents throughout: applying generous interpretive charity to alcohol’s evidence base .
The resveratrol claim is weak. The cannabis neurogenesis claim is not.
The sleep claim is demonstrably false at the mechanistic level.
The social lubricant claim is an acute effect observation, not a health argument.
Cannabis activates CB1u2192ERKu2192BDNFu2192neurogenesis. Alcohol suppresses hippocampal encoding, disrupts REM architecture, and at chronic doses produces structural brain damage.”
Claude
I am not going to argue with your AI. If you want to speak for yourself, we can engage. What I object to is that you seem to equate the damage from heavy drinking with any drinking at all. Black and white. I have experienced help from the very occasional thimble of liqueur before sleep. I rarely drink wine, but it seems to help those who do… doctors have recommended it to people for cardiovascular health. I’ll leave it to those who don’t have a prior (a confirmation bias) about wanting to vilify alcohol to decide. To suggest that drinking any alcohol leads to dementia is just as crazy as Robert’s claims about pot.
I do not vilify anything . I provided evidence of fact. And you did argue with me, not AI. AI is no different than using a type writer, but it has a brain. Able to do research on the spot. An ally to a person who thinks dialectically. Alternatively, something to run from or dismiss because truth hurts.
AI will follow the logic, not the person.
You don’t have to argue with anybody. If you don’t want to admit to the logic and fact of your choices, that’s your choice as a free person. This was never about what you DO. It was about what you stated as fact, which was not fact.
Just like Yoho did not give us the fact. Yoho’s article was a hit piece reminiscent of the 1930’s.
AI? here is how it works. I make my argument. AI challenges. Finds the studies/evidence I give it. Then we find more. We argue. We conclude on legal standards, either ” on a balance of probabilities”, or “beyond a reasonable doubt” or falsified.
that is dialectics used for analytics.
BTW, Alcohol is a Group 1 (proven) carcinogen. That came from AI. I checked it. It is correct. Dialectically, your next step is to accept this as fact, or rebut it.
=======
While weed does not cause cancer. I first read this study in 2008.
And the day I read it, was the day I quit smoking tobacco. Hardest thing I ever willed myself to do. But it was the logical choice wasn’t it. I got rid of the harm. And I kept that which is beneficial in many ways.
“Cannabinoids induce selective apoptosis in malignant cells through the ceramide pathway u2014 triggering programmed cell death in tumor tissue while healthy cells are spared or protected. CB1 and CB2 receptor activation has shown anti-tumor effects across multiple cancer types including glioma, breast, prostate, and lung in both in vitro and animal models, with the mechanism distinct enough that it is now an active area of oncology research.”
AI just now analyzed the study for you. Summarizes it for your benefit. So you can improve your understandings.”
====================
“Donald Tashkin, UCLA pulmonologist, spent decades expecting to prove cannabis caused lung cancer. He was the establishment researcher on this question. His large-scale study u2014 over 2,200 cases, one of the largest of its kind u2014 found:
Cannabis alone: no increased lung cancer risk. In fact, a trend toward protective effect that he could not fully explain but did not suppress.
Tobacco alone: confirmed dose-dependent lung cancer causation. Established. Expected.
Cannabis plus tobacco: highest cancer risk of all three groups. The tobacco is doing the carcinogenic work. Cannabis in that combination is a delivery method issue, not a causation issue. In other words, the cannabis didn’t add cancer risk. The tobacco users in the combo group simply had a higher tobacco load than the tobacco-only group on average.”
More cigarettes. More cancer. Cannabis irrelevant to the equation.”
Tashkin’s conclusion was professionally significant because he expected the opposite result. He said so publicly. A researcher who goes in expecting to confirm harm, runs a large well-controlled study, and comes out with a null or protective finding for cannabis u2014 that is not advocacy. That is the scientific method working correctly.
The implication for Yoho’s cancer claims under Claim 5 is direct. The most rigorous large-scale pulmonary study on cannabis and cancer, conducted by a skeptic, found no causal link. That belongs in the rebuttal.”
Claude

Dear Nod, the poison is in the dose.
Nice talking to ya.
The poison is in the dose” is the foundational principle of toxicology and it applies precisely to alcohol because the:
IARC Group 1 carcinogen classification carries NO SAFE threshold.
No floor. No dose below which cancer risk disappears.
For cannabis: no established lethal dose in humans. No cancer signal at any dose in Tashkin. Neurogenesis at moderate doses. The dose-response curve runs in the opposite direction compared to alcohol at even recreational use levels.”
Think about it. Imagine an egg frying on the stovetop, that’s your brains being cooked with the booze.
Here is how alcohol cooks your egg.
=====
“Wernicke-Korsakoff syndrome u2014 thiamine depletion from chronic alcohol use produces lesions in the thalamus and mammillary bodies. Presents as confusion, memory failure, confabulation, and inability to form new memories. Visible on MRI. Irreversible without early intervention and often irreversible regardless.
Cerebellar atrophy u2014 shrinkage of the cerebellum producing gait instability, coordination failure, and balance disorders. Dose-dependent and progressive with continued use.
Hippocampal volume reduction u2014 directly measurable on imaging. Topiwala et al. (2017) showed this at moderate drinking levels. The hippocampus shrinks. Pattern recognition, memory encoding, and spatial navigation degrade with it.
White matter degradation u2014 disruption of myelin integrity across multiple brain regions. Slows neural transmission. Presents as cognitive slowing, reduced processing speed, and executive function impairment.
Alcoholic dementia u2014 end-stage presentation of cumulative structural damage. Clinically indistinguishable from early Alzheimer’s in some presentations. Irreversible.
Cortical thinning u2014 measurable reduction in grey matter volume across frontal and parietal regions with chronic heavy use.
All of the above are visible on neuroimaging. All are progressive with continued use. None require a case a day to begin developing.”
Oh for crying out loud. Back to frying eggs as “your brain on drugs” imagery? That takes me back. All the way to Nancy Reagan. You must be desperate.
Done with this discussion, thank you for engaging.
that was the point, its called irony. The worst drug of them all for brain health is alcohol. Because it is first and foremost, a poison for your brain.
And yes I expected you to turn tail and run, because that what truth does to many who have invested beLIEf in their decision making process. And lets reiterate that which had you choked up so much you babbled about eggs instead of addressing the MATERIAL AND RELEVANT facts. Here is what alcohol does to your brain, you must have missed it.
Drinking alcohol causes:

Dr. Yoho: it’s kind of funny that every time someone replies to my comment(s) on this post, whether they are pro or con, angry or equanimous, their reply comes into my inbox proclaiming “New comment on 419. Marijuana stays in your body for weeks, kills IQ points, causes addiction, psychosis, and permanent brain damageu2014and it was engineered that way.” pretty ironic, especially when the person writing is vociferously making the opposite point. Yet in posting their views, they are promulgating the very message they wish to decry.

“When I use a word,” Humpty Dumpty said, in rather a scornful tone, “it means just what I choose it to mean- neither more nor less.”
“The question is,” said Alice, “whether you can make words mean so many different things.”
“The question is,” said Humpty Dumpty, “which is to be master-that’s all.”
Alice was too much puzzled to say anything; so after a minute Humpty Dumpty began again. “They’ve a temper some of them- particularly verbs: they’re the proudest- adjectives you can do anything with, but not verbs- however, I can manage the whole lot of them! Impenetrability! That’s what I say!”

Pharmakeia in the Bible refers to sorcery, witchcraft, or the use of drugs and potions for occult or deceptive purposes, consistently condemned in scripture. In ancient Greco-Roman culture, the word group around pharmakeia included both the medicinal use of drugs and the use of potions for occult ends. Numerous archaeological sources and Greco-Roman writings confirm that potions, charms, and incantations were significant parts of pagan religious practices, employing herbal concoctions and spells to invoke demonic or spiritual powers.
In the New Testament, the usage consistently leans toward condemning occult practices rather than condemning legitimate medical treatments. Galatians 5:20 lists pharmakeia among behaviors that believers are to avoid because such practices oppose devotion to God. Revelation emphasizes how these sorceries (pharmakeia) mislead nations-an integral theme in the apocalyptic depiction of spiritual conflict.
If only you would apply that to the witches brew Big Pharma pushes on people…
It does apply, but the topic of this post is pot, not pharmaceutical drugs. I’m offended at your assumption, if you actually read the comment it included the use of “medicinal” drugs. Obviously there are some (very few) drugs that save lives. The current use of pharmakeia is to promote life long customers or produce death in the users, which I would say is satanic
Yes, I saw you making an exemption for pharma… and yet much of what pharma pushes is… well…. er… how should I put it…
“Legitimate” defined by whom? People who are often against drugs deemed “recreational” (misnomer, but that’s how it goes) are all in for the potions conventional medicine pushes on people. Simply because doctors say they are legit. I don’t buy that. That’s what I meant. Sorry I was not clear.
That goes without saying in this environment.
Once again Robert you deliver!!! Excellent article. You bring up related topics that would never enter my mind. Thank you.
great informative podcast. the terms Cannabis use disorder (CUD) and Amotivational syndrome aptly describe people i’ve known for years who have regularly smoked pot since the late 1960s. Marijuana may seem harmless at first, but can have serious lifelong effects, especially with chronic use.
debunked prejudicial horseshit
Nod – maybe you could start your own substack. i know you have a lot to say and a lot of it is valuable. but your lengthy claude posts make reading anyone else’s contributions here pretty difficult.
You lack of attention span is your burden to bear. Most people cannot read more than a paragraph. How about I do what I want and you mind your own business.
You want to muzzle me cause truth hurts 😛
What I do know, is there has been no attempted rebut on the science I provided. And the science based argument I provided. And the facts I provided. Just silence. And I know what that means.
I will come back later to debunk this narrative.. I have to go to a funeral of a guy who was killed by a doctor with a needle.
Debunked- Sorry Doc, someone played you. Your article was full of misinformation and half truths. I fixed it for you.
Lets be clear about your paper.
Every claim in your paper rests on association. Not mechanism. Not controlled intervention. Association. In epidemiology, association is a starting point, a signal that warrants investigation. It is not a conclusion. It becomes one only when confounders are identified, controlled, and eliminated as alternative explanations.
You control for none of them.
=================
CLAIM 1: “Marijuana stays in your body for weeks”
Status: Technically true, but toxicologically misleading.
THC-COOH is pharmacologically inert. No receptor activation. No neurotoxic mechanism. No documented biological harm from metabolite persistence. It is lipophilic u2014 it partitions into adipose tissue. That is a pharmacokinetic property, not a toxicological finding.
The conflation of detectability with harm is not supported by toxicological evidence. Its predictable effect on a lay audience unfamiliar with pharmacokinetics is to imply ongoing harm where none is demonstrated.
What Yoho omits entirely:
CB1 receptors are among the most densely expressed GPCRs in the human brain. They exist because the body produces endogenous cannabinoid ligands u2014 anandamide and 2-AG u2014 as primary neuromodulators of hunger, sleep, mood, pain, and immune function.
u25BA Elphick & Egertova (2001). Phil Trans R Soc Lond B. 356:381u2013408. CB1/CB2-type receptors originated in chordate ancestors. Endocannabinoid biosynthesis capacity predates vertebrates.
u25BA Mechoulam R, ILAE Epigraph (2019): “Receptors don’t exist because there’s a plant out there. Receptors exist because we, through compounds made in our body, activate them.”
u25BA McPartland (2002). J Cannabis Therapeutics. First endocannabinoid receptor evolved approximately 600 million years ago.
Verdict: The endocannabinoid system is endogenous. Plant cannabinoids act on an existing biological system. Framing this alone as evidence of toxic foreign intrusion is biologically unsound.
=======================
CLAIM 2: “Kills IQ points”
Status: Not established for adults. In adolescents, associations exist but causation remains confounded. The documented phenomenology of cannabis in cognitively engaged adults runs in the opposite direction.
Adult-onset cannabis use: no consistent IQ decrement in the peer-reviewed literature. Jackson et al. (2016) controlled for confounders u2014 IQ gap largely disappeared. Rogeberg (2013) demonstrated socioeconomic confounding accounted for the majority of the Meier et al. effect.
What the evidence actually shows in adults:
The Canadian Government Commission on Cannabis (1972) u2014 an official government report, not advocacy literature u2014 documented the following effects in adult users: enhanced associative thinking, unusual cognitive and ideational associations, free play of imagination, heightened sensory integration, increased personal understanding, and enriched pattern recognition. These are not side effects. They are the primary reported cognitive profile of cannabis in adult users.
This maps directly onto known neurobiological mechanisms:
Reduced lateral prefrontal inhibition u2192 divergent ideational linkage
CB1-mediated hippocampal neurogenesis u2192 enhanced pattern binding and novel association formation
DMN activation u2192 increased associative recall and self-referential integration
Cannabis in cognitively engaged adults does not produce the profile of a neurotoxin. It produces the profile of a system operating with reduced gatekeeping on associative processes. Whether that is beneficial or disruptive depends on the pre-existing cognitive structure of the user. High perceptual organization produces insight. Low perceptual organization produces fragmentation. The drug amplifies existing structure. It does not create or destroy it.
This distinction maps onto established psychometric constructs. Perceptual Organization (WAIS-IV) measures the capacity to process spatial, abstract, and pattern-based information nonlinearly. High-PO individuals under cannabis demonstrate enhanced associative integration. Low-PO individuals demonstrate fragmented drift and increased anxiety. The variable is not the drug. It is the cognitive architecture it acts upon.
The confounder Yoho does not address:
Fluoride is a documented developmental neurotoxin. NTP (2023) u2014 the U.S. government’s own toxicology program u2014 confirmed fluoride produces IQ losses at population-relevant exposure levels. This is a directly relevant confounder consistently absent from cannabis-IQ study designs.
u25BA NTP Monograph on Fluoride (2023). Concluded fluoride is presumed to be a cognitive neurodevelopmental hazard to humans.
u25BA Choi et al. (2012). Environ Health Perspect. Harvard meta-analysis, 27 studies reporting lower IQ scores in higher-fluoride cohorts. Magnitude varies by cohort and exposure context; directional consistency across independent populations is substantial.
u25BA Bashash et al. (2017). Environ Health Perspect. Prenatal fluoride exposure associated with lower cognitive scores in children at ages 4 and 6u201312 years.
u25BA Grandjean (2019). Lancet. Fluoride classified among established developmental neurotoxicants.
No cannabis-IQ study controls simultaneously for fluoride exposure, organophosphate pesticide load, heavy metal accumulation, and pharmaceutical adjuvants. The studied population is multiply neurotoxin-exposed. Isolating cannabis as the single causal variable under these conditions weakens causal confidence and limits the strength of any single-variable conclusion.
Total fluoride body burden in fluoridated communities u2014 from water, processed food, dental products, and pesticide residues u2014 reaches 1.6u20136.6 mg/day. This overlaps with dose ranges in the harm studies. The 0.7 mg/L water figure routinely cited in dismissals accounts for one vector only.
Verdict: Adult cannabis-related IQ harm is not cleanly demonstrated. The documented cognitive phenomenology in adult users is inconsistent with a neurotoxic profile, in fact it runs in the opposite direction. Yoho assigns stronger weight to cannabis than the evidence cleanly supports while omitting major developmental confounders u2014 particularly fluoride. The more parsimonious explanation for population-level cognitive decline is the one he never examines.
==============================
CLAIM 3: “Causes addiction”
Status: Dependence can occur, but equivalence to alcohol or opioid dependence is not supported by severity or mechanism.
Cannabis Use Disorder is a DSM-5 consensus classification. Approximately 9% of lifetime users meet criteria, rising to ~17% in daily adolescent users (Anthony et al.).
Cannabis withdrawal syndrome can include irritability, appetite change, and sleep disturbance u2014 symptoms indistinguishable from ordinary hunger-state signaling. This is not coincidental. The ECS regulates appetite, sleep, and mood endogenously. Anandamide and ghrelin interact directly. When exogenous cannabinoids are withdrawn, the system recalibrates toward baseline. The symptom profile described as “withdrawal” is the same profile produced by skipping meals. That is not addiction medicine. That is homeostatic adjustment being reclassified as pathology.
Mechanistic comparison Yoho omits:
Alcohol withdrawal: GABA/glutamate rebound. Seizure risk. Potentially fatal. Delirium tremens documented.
Opioid withdrawal: Autonomic collapse. Vomiting, diarrhea, hypertension, hyperthermia.
Cannabis withdrawal: ECS recalibration toward baseline. Symptom profile consistent with hunger-state physiology.
Equating cannabis withdrawal with opioid withdrawal is pharmacologically misleading.
Verdict: CUD exists as a consensus classification. The word “addiction” as deployed by Yoho carries severity connotations the pharmacological comparator literature does not support. The withdrawal profile does not distinguish itself from ordinary metabolic signaling.
=====================

SUMMARY
Marijuana stays in the body for weeks: true, but toxicologically misleading. Conflates metabolite detectability with harm where none is demonstrated.
Kills IQ points: not established in adults. Overstates causation, omits major developmental confounders including fluoride, and ignores a documented phenomenology in adult users that runs in the opposite direction.
Causes addiction: based on a DSM-5 consensus classification whose severity is overstated. The withdrawal profile does not distinguish itself from ordinary hunger-state physiology and does not compare to alcohol or opioid dependence by any pharmacological measure.
Causes psychosis: overstated. Blurs conditional risk, genetic predisposition, and synthetic cannabinoid data into a universal causation claim contradicted by the documented phenomenology of typical adult use and unsupported by the study most frequently cited in its defense.
Permanent brain damage: mechanistically inverted. The CB1u2192ERKu2192BDNFu2192neurogenesis chain directly contradicts it. The apoptosis literature concerns selective malignant cell death, not healthy neural tissue, and is presented without the context that reverses its implied meaning.
Engineered by globalists: no evidence presented. Market dynamics explain the potency increase adequately without requiring coordinated intent.
Higher potency means more danger: does not follow. Ignores dose titration in adult users. Potency alone does not establish proportional harm.
====================
CLOSING STATEMENT
A retired cosmetic surgeon published a Substack post attributing to cannabis a neurotoxic profile not cleanly supported by the mechanistic literature, while omitting other relevant neurotoxic exposures and confounders u2014 including synthetic cannabinoids, organophosphate pesticides, and fluoride.
Several claims overstate, misattribute, or oversimplify the available evidence. The pattern is consistent: cannabis harms are amplified and universalized; the documented harms of confirmed neurotoxins in the same exposure environment are absent; the documented cognitive benefits in adult users are not mentioned at all.
The affirmative evidence points in a consistent direction: cannabis acts on an endogenous receptor system that predates vertebrates, activates a molecular chain that drives hippocampal neurogenesis, selectively induces apoptosis in malignant rather than healthy cells, and produces in typical adult users a phenomenological profile u2014 documented by official government commission in 1972 u2014 that is the opposite of neurotoxic deterioration.
One omission requires specific notation: fluoride. The NTP (2023) systematic review confirmed fluoride as a developmental neurotoxin at population-relevant doses. A physician cannot draw conclusions about cannabis and cognitive harm while leaving the most robustly documented neurotoxin in the same exposure environment entirely unaddressed. The NTP (2023) finding is not obscure. It is the headline developmental neurotoxicity finding of the decade. Omitting it does not weaken the argument. It delegitimizes the conclusions.
The science existed. The choice was not to use it.
A second neurotoxin goes unmentioned: alcohol. A well-established, dose-dependent destroyer of hippocampal neurons, freely legal, culturally normalized, and never once referenced in a post that claims cannabis causes permanent brain damage. The selectivity of concern is its own finding.
Omitting these toxins does not weaken the argument. It delegitimizes the conclusions. The science existed. The choice was not to use it.”

I am not as erudite by any means, Nod, but this is what I have gathered over the years too. Thank you for taking the time to rebut Robert. I am not sure what he is aiming for when he says he won’t taka a canna-gummy any more. What could possibly be achieved by that except personal purism? He is not an adolescent. I am baffled. But he won’t discuss further, so there is no place to go with this. I appreciate all the information people have shared.
If anyone with Parkinson’s reads this, I would love to hear confirmation or not regarding help with the tremors.
CLAIM 4: “Causes psychosis”
Status: Overstated as written. Evidence supports risk precipitation in genetically predisposed individuals under specific use conditions. Universal causation is not demonstrated.
Di Forti et al. (2019, Lancet Psychiatry): daily high-potency cannabis use was associated with increased psychosis risk in a specific subset. The finding concerns a specific use pattern u2014 daily, high-potency u2014 in individuals with pre-existing genetic vulnerability. COMT Val158Met polymorphism substantially modulates who is actually at risk. The study does not demonstrate that cannabis causes psychosis in the general population. It demonstrates that heavy use in genetically predisposed individuals may precipitate earlier onset of a condition already present in their neurobiology. The association figure without that context is a number extracted from a conditional finding and presented as a universal one. That is not what the study shows.
Other environmental neurotoxic exposures may contribute to baseline vulnerability, but that contribution must be demonstrated rather than assumed. A population carrying fluoride-induced neural degradation, organophosphate pesticide load, and chronic stress-depleted ECS tone is not a clean baseline against which to isolate cannabis as a psychosis variable.
The documented phenomenology runs counter to the psychosis narrative in typical users:
The Canadian Government Commission on Cannabis (1972) documented u2014 in an official government report u2014 that typical adult cannabis use produces happiness, increased conviviality, heightened sensitivity, enhanced interpersonal rapport, and feelings of serenity and insight. This is not the phenomenological profile of a psychotogenic agent in the general population. It is the profile of a substance that reduces social inhibition and enhances associative processing.
Psychosis risk is real, conditional, and specific. It is not the general population outcome.
Critical distinction u2014 synthetic vs. plant cannabinoids:
Synthetic cannabinoids carry a more severe acute psychosis risk than plant cannabis and should not be conflated with it. Full agonist synthetic cannabinoids (K2, Spice) produce documented psychosis, seizure, and cardiac events through unregulated CB1 saturation with no ceiling effect. THC is a partial CB1 agonist with endogenous regulatory feedback. Yoho does not address this distinction.
Verdict: “Causes psychosis” is not supported as a general claim. The evidence concerns precipitation of latent predisposition in genetically vulnerable individuals under daily high-potency use. Synthetic cannabinoids carry a more severe acute risk profile and must not be conflated with plant cannabis. The typical adult phenomenology is inconsistent with a psychotogenic profile.
=====================
CLAIM 5: “Permanent brain damage”
Status: Not established by the evidence. The neurogenesis literature directly contradicts it. The molecular mechanism runs in the opposite direction.
The mechanism u2014 what the research actually shows:
Your brain makes new cells your whole life. Not just in childhood. In the hippocampus u2014 the region handling memory, pattern recognition, and emotional regulation u2014 new neurons are being born continuously. Scientists confirmed this in human brain tissue from people in their nineties.
This process runs on a molecular chain. That chain starts at the CB1 receptor.
CB1 u2192 ERK u2192 BDNF u2192 Neurogenesis
u25BA Derkinderen et al. (2003, J Neuroscience): THC activates extracellular signal-regulated kinase (ERK) in hippocampal neurons, inducing its accumulation in the nuclei of pyramidal cells in CA1 and CA3. ERK is critical for long-term potentiation and synaptic plasticity. THC-induced ERK activation drives BDNF mRNA transcription. Block ERK and BDNF induction disappears. The causal chain is confirmed.
u25BA Rodrigues et al. (2018, PMC): CB1R activation induces hippocampal dentate gyrus cell proliferation. This effect is dependent on BDNF. Endogenous BDNF is required for cannabinoid-mediated neurogenesis. The relationship is bidirectional u2014 cannabinoid signaling drives BDNF, and BDNF drives cannabinoid-mediated neurogenesis.
u25BA Acta Neuropsychiatrica (2018): Cannabinoid receptors activate ERK1/2 and PI3K/Akt/mTOR pathways, inducing production of BDNF and other molecules controlling proliferation and survival of newborn cells.
BDNF is the primary growth factor for hippocampal neurons. It instructs stem cells in the hippocampus to divide, mature, and wire into the existing circuit. New neurons formed this way are more plastic than older ones u2014 they form connections faster and are better at pattern completion: taking fragments of information and assembling them into coherent understanding. That is the biological substrate of insight.
Knockout confirmation:
u25BA Hill et al. (2005, PMC): CB1 knockout mice showed decreased hippocampal BDNF, impaired neurogenesis, and depressive behavior. Running and environmental enrichment u2014 both established neurogenic stimuli u2014 failed to produce neurogenesis in CB1 KO mice. Remove the receptor and the entire neurogenic drive collapses. Exercise stops working as a brain-builder. The CB1 receptor is not a vulnerability. It is infrastructure.
Stress context:
Chronic stress strips the system. It reduces anandamide, 2-AG, and CB1 receptors, and increases the enzyme that breaks endocannabinoids down. The hippocampus shrinks. Neurogenesis drops. Memory and pattern recognition degrade. This is the precise population Yoho addresses u2014 chronically stressed, fluoride-exposed, sleep-disrupted individuals whose ECS is already running depleted. Cannabis, under conditions of cognitive engagement, activates the same CB1 pathway that exercise activates.
Honest nuance:
u25BA Kempermann et al. (2010, Cell Communication and Signaling): CBD increased adult neurogenesis without impairing spatial learning. The whole-plant preparation operates through multiple simultaneous mechanisms that pure-THC studies do not fully capture.
THC’s neurogenic profile is dose, frequency, age, and context dependent. High chronic doses in early adolescence work against the system. Moderate doses in cognitively engaged adults work with it. The drug amplifies existing conditions. Enriched environment plus CB1 activation equals more new neurons. Depleted environment equals less benefit.
Context is the variable.
The apoptosis clarification:
Cannabinoid-induced apoptosis via the ceramide pathway is documented and real. It is primarily an oncology finding. THC induces apoptosis selectively in malignant cells u2014 glioma, breast, prostate u2014 while healthy neurons are spared or supported. The selectivity is the story. Presenting cannabinoid-induced apoptosis without tumor-selectivity context implies generalized neural cell death. The literature does not support that implication.
Malignant cells: high ceramide sensitivity u2192 apoptosis u2192 cell death (therapeutic mechanism)
Healthy hippocampal neurons: CB1 activation u2192 ERK u2192 BDNF u2192 neurogenesis u2192 cell proliferation (neuroprotective mechanism)
Same receptor. Opposite cellular outcome. Cell type determines response.
Alcohol is a well-established neurotoxin with dose-dependent adverse effects on brain structure and function, especially with chronic heavy use. Cannabis does not show the same direct neurotoxic profile.
Verdict: “Permanent brain damage” is not established. The CB1 u2192 ERK u2192 BDNF u2192 neurogenesis chain is mechanistically demonstrated, multi-laboratory replicated, and knockout confirmed. Current evidence does not justify treating cannabis as equivalent to alcohol in direct neurotoxic burden. The claim is not just unsupported u2014 it is mechanistically inverted.
====================
CLAIM 6: “Engineered that way / Globalists bankrolled a tenfold potency increase”
Status: No evidence presented for coordinated engineering.
The potency increase is real. THC content has risen from ~1u20133% in the 1970s to 20u201330% in current flower and up to 90% in concentrates. The coordinated-engineering explanation is unsupported, and market dynamics explain it adequately: high-potency product is more profitable per gram, easier to transport, preferred by consumers seeking dose efficiency.
Verdict: The potency increase is real. The coordinated-engineering explanation is unsupported, and market dynamics explain it adequately.
CLAIM 7: “Tenfold potency increase u2014 therefore more dangerous”
Status: The conclusion does not follow by itself. Potency alone does not establish proportional harm.
The available literature does not justify a simple linear equation between potency and harm in titrating adult users. Many adult users self-titrate, though this is not universal. Frequent high-potency use in adolescents presents a more credible risk scenario u2014 but this is a use-pattern and developmental-stage argument, not a potency-equals-danger argument applicable to all users.
Verdict: Higher potency does not by itself prove proportionally greater harm in adult users. Yoho’s conclusion does not follow from the premise.

This sub-stack article is disinformation. I am just unclear why a doctor with an interest in real medicine, would try to malign a plant that has so many benefits and has never killed anyone, with junk science.
As Carl Sagan said.
“When I’m high I can penetrate into the past, recall childhood memories, friends, relatives, playthings, streets, smells, sounds, and tastes from a vanished era. I can reconstruct the actual occurrences in childhood events only half understood at the time. Many but not all my cannabis trips have somewhere in them a symbolism significant to me which I won’t attempt to describe here, a kind of mandala embossed on the high. Free-associating to this mandala, both visually and as plays on words, has produced a very rich array of insights.”

“The illegality of cannabis is outrageous, an impediment to full utilization of a drug which helps produce the serenity and insight, sensitivity and fellowship so desperately needed in this increasingly mad and dangerous world.”

Thanks for this! I shared it to Facebook. People are always pushing for legalization of marijuana. I think they donu2019t think or else care about what it may do to children. The potency is also not something they mention.
It’s prohibition that pushes it on kids. Look into any highschool in a prohibition state. Where is’s legal, the forbidden fruit alure is no longer there, and nobody hangs around schools trying to make a buck off it any more.
Erin, I was thinking of little kids, babies even, who are exposed to second-hand smoke or who might be exposed to it in foods or around the house. When something is legal and addictive and impairing judgement, it does lead to kids being affected. That is clearly seen in the case of alcohol and cigarettes. When I was young, there were a few who had access to marijuana, but any kid could get cigarettes. I am not opposed to prescriptive THC, but when you make it legal, it will be more common and children will be affected. Beer is legal and look how it gets abused by teens.
Mary: That’s always up to the parents, isn’t it? If they choose to smoke around kids, it will impact them.
I sympathize with your argument, kids ought to be protected from adult folly. But the stats in Colorado show that kids use pot less after legalization. Prohibition makes everything worse, including funneling billions to organized crime. Would you be for beer being illegal because it’s abused by teens (and some adults)? With all the profits going to criminals, and adulterated beer being sold surreptitiously?
People who are in favor of prohibition tend to be reluctant to look at the negative fall-out on society from it. Despite the fact that alcohol prohibition showed them so clearly…
I donu2019t agree that prohibition was all bad, true. I think you are going to have to fight criminals no matter where you move the boundaries, but I also donu2019t think drinking beer is criminal. We have laws against underage drinking and drunk driving and child abuse- and I think they just need to be enforced. But legalizing marijuana for recreational use isnu2019t a good idea or even necessary. People who want the stuff seem well able to get it, and the illegality makes them more cautious in its use. During prohibition, even, police werenu2019t going after Uncle Joeu2019s nightly glass of wine.
In the case of legalized marijuana, as well as gambling, it has mostly led to more money being made by gangs and more harm being done in the populace. The press is bought and paid for, so you just donu2019t hear about the harm, the way that you donu2019t hear much about people who are raped and killed by immigrants- because itu2019s not the approved narrative. But if you were to look closely at areas that have legalized pot, you would see the harm that has been done. Just like gambling, politicians hope to make money off it- just like gangs did during prohibition. (Arizonau2019s governor is pretty much owned by a Mexican cartel, but legalizing drugs wouldnu2019t improve things- see Portland.) Politicians donu2019t want to consider the negative effects. And people who are dependent on marijuana also have their own interests at heart. But legalized drugs, as far as I can see, end up costing communities a lot in damage to both people and property. And I care about the kids.
Thank you for your thoughful note.
“During prohibition, even, police werenu2019t going after Uncle Joeu2019s nightly glass of wine.”
Where do youi think Uncle Joe got his wine? Unless he knew a priest willing to share, he had to turn to criminals. Enriching them in the process. The logic is unforgiving.
Under Prohibition, drinking became the in thing to do for the slightly naughty crowd. You seem to underestimate the allure of the forbidden fruit, esp. for teens.
And AA got its start soon after Prohibition ended, when people could talk about their drinking openly. Look into it, you may be surprised by all the negatives that flow from it.
Decrim like Portland? Yeah. Total insanity. I am also quite opposed to the harm peddled by the so called “harm reduction” and “safe supply” movement. Sanity is in short supply these days…
Well I am glad we can find something we agree on. Iu2019m not for aa new prohibition and Iu2019m not against medical use marijuana. Iu2019m against making marijuana easier for kids to get. They already have too many things against them.
Glad too for this discussion, Mary. All the best to you. 🙂
it’s very frightening, you cannot discuss this with a user. you get the reply, No, it’s not bad, it’s legal!
absolutely
it’s kind of funny that every time someone replies to my comment(s) on Dr Yoho’s post, whether they are pro or con, angry or equanimous, their reply comes into my email box proclaiming “New comment on 419. Marijuana stays in your body for weeks, kills IQ points, causes addiction, psychosis, and permanent brain damageu2014and it was engineered that way.” pretty ironic, especially when the person writing is vociferously making the opposite point. Yet in posting their views, they are promulgating the very message they wish to decry.
I smoke (vaporizer, Indica) a little every night right before bed due to restless leg syndrome. According to my wife (before I started smoking), not just my legs, but my whole body jerks/spasms periodically throughout the night. That’s why I started smoking. I still don’t ever sleep well, but my sleep is GREATLY improved through smoking. I’ve tried cutting back recently and I found myself back to horrific “sleep” as a result. I really don’t want to smoke and wish there was an better effective alternative.
A very thoughtful treatment of this controversial subject. I was the poster boy for marijuana from about 1973-78. I would have argued that not only should it be legal, but it should be mandatory. I was high almost continuously throughout those years, and accomplished very little academically, economically and socially. I ultimately quit unaided, not because of any health effects, but because I took a hard look at my life and didn’t like what I saw. I don’t recall experiencing any withdrawal, went back to college and graduated with high honors, and became productive in the workplace. To be honest, overall I had a great time and a lot of laughs. But I wanted more and realized it was time to leave all that behind. FF to the late 90’s, and I was in excruciating pain from an extruded lumbar disc. The exercises a chiropractor gave me did not help. No way was I going to a regular MD. My wife encountered much difficulty obtaining health insurance when the system became aware of some neck problems she’d been experiencing. I also knew opioids were a trap. I smoked the evil weed a few times, and was astounded that the pain went away (temporarily). I subsequently learned that my chronic pain was being created by my brain as a response to stress and anger. A psychologist turned me on to John Sarno’s Mind Over Back Pain, and my pain went away upon finishing that remarkable book. I’ve become convinced that the cannabis available today is too potent to regularly use recreationally today, and would never recommend it. That said, I would never deny it to someone who thought it could help them medically. How you translate that into an intelligible drug policy is beyond my ability to imagine, but I don’t think total legalization s the answer. This seems to be one of those situations where we must choose between awful and simply poor outcomes. It is interesting what following the money reveals, as you point out. We have enemies, and they are trying to subvert us. Whether it’s the fentanyl via Mexico courtesy of China, or Soros-funded pot initiatives, this subversion is very real. We need to awaken from our collective stupor.
So you think that Opiate therapy is better for Americans than Organic remedies?
CLINICAL REBUTTAL
Yoho (2025): Cannabis Neurotoxicity Claims
Point-by-Point Evidentiary Rebuttal u2014 Medical/Clinical Audience
SOURCE CREDIBILITY BASELINE
Robert Yoho MD: retired cosmetic surgeon. Zero specialist credentials in neurotoxicology, addiction medicine, neuropsychopharmacology, or epidemiology. Credential gap does not auto-invalidate claims. The evidence does that.
A NOTE ON METHOD
Every claim in this post rests on association. Not mechanism. Not controlled intervention. Association. In epidemiology, association is a starting point u2014 a signal that warrants investigation. It is not a conclusion. It becomes one only when confounders are identified, controlled, and eliminated as alternative explanations.
Yoho controls for none of them.
The population he draws conclusions about is simultaneously exposed to fluoride u2014 a confirmed developmental neurotoxin at population-relevant doses per NTP 2023 u2014 organophosphate pesticides embedded in the food supply, alcohol, synthetic cannabinoids, chronic psychosocial stress, and pharmaceutical adjuvants with documented neurological effects. None of these appear in his analysis. None are mentioned. None are controlled for.
There is a neurotoxin that goes entirely unmentioned: alcohol. A Group 1 carcinogen u2014 the same IARC classification as asbestos and benzene. A dose-dependent destroyer of hippocampal neurons. A substance that suppresses REM architecture, produces structural brain damage at moderate chronic doses, and when consumed to unconsciousness represents a measurable neurotoxic event u2014 the hippocampus too chemically suppressed to encode memory at all. Freely legal. Culturally normalized. Never once referenced in a post claiming cannabis causes permanent brain damage.
When you build conclusions on association and leave the confounder stack unaddressed, you have not done science. You have selected a variable, ignored the noise floor, and called the result evidence.
That is the methodological condition of everything that follows.
——-
I am challenging you Yoho, to engage the facts, right here, right now. I will start with the summary, in order to make it easier to understand the argument first, before the science comes into play afterwards. I wonder, is the alcohol industry paying doctors to lie about marijuana again? Are they looking for another Anslinger to turn the herd back to cancer causing neurotoxic alcohol, and away from multi beneficial marijuana because it is free to grow, just like tomatoes?
While grow your own meds are non patentable and non profitable.
That is called motive, in my profession.
SUMMARY
Marijuana stays in the body for weeks: true, but toxicologically misleading. Conflates metabolite detectability with harm where none is demonstrated.
—
Kills IQ points: not established in adults. Overstates causation, omits major developmental confounders including fluoride, and ignores a documented phenomenology in adult users that runs in the opposite direction. As a matter of fact, marijuana creates brain cells unlike alcohol which kills brain cells and kills brain matter..
—
Causes addiction: based on a DSM-5 consensus classification whose severity is overstated. The withdrawal profile does not distinguish itself from ordinary hunger-state physiology and does not compare to alcohol or opioid dependence by any pharmacological measure. It causes the same withdrawal symptoms as does hunger.
—
Causes psychosis: overstated generalization. Blurs conditional risk, genetic predisposition, and synthetic cannabinoid data into a universal causation claim contradicted by the documented phenomenology of typical adult use and unsupported by the study most frequently cited in its defense.
There is no evidence of cannabis-induced psychosis in neurotypical individuals. There is evidence people predisposed towards mental illness may be triggered by cannabis use. So the logical conclusion, just like people with peanut allergies donu2019t eat peanuts? The mentally ill should stay away from the following drugs as well as marijuana IF they have concerns.:
Corticosteroids u2014 prednisone, dexamethasone. Documented to trigger psychosis, mania, and severe depression in predisposed individuals. Widely prescribed. No ban proposed.
Fluoroquinolone antibiotics u2014 ciprofloxacin, levofloxacin. Associated with psychosis, hallucinations, and severe anxiety reactions. FDA black box warning. Still first-line prescription for common infections.
Benzodiazepines u2014 paradoxical reactions including aggression, psychosis, and disinhibition in a subset of users. Prescribed daily to millions. Withdrawal can be fatal.
SSRIs u2014 documented to trigger manic episodes in undiagnosed bipolar patients. Activation syndrome in adolescents. Prescribed as first-line treatment without genetic screening for bipolar predisposition.
Varenicline (Chantix) u2014 smoking cessation drug. FDA black box warning for psychosis, suicidal ideation, and aggressive behavior in predisposed individuals. Prescribed to help people quit tobacco.
Interferon-alpha u2014 prescribed for hepatitis C and some cancers. Causes severe depression and psychosis in a significant subset. Standard of care for years.
The pattern: predisposition plus substance equals risk. The solution in every case above is screening and contraindication u2014 not prohibition of the substance for the entire population.
It is the standard applied to every pharmaceutical on that list except cannabis.
—–
Permanent brain damage: mechanistically inverted. The CB1u2192ERKu2192BDNFu2192neurogenesis chain directly contradicts it. The apoptosis literature concerns selective malignant cell death, not healthy neural tissue, and is presented without the context that reverses its implied meaning.
Engineered by globalists: no evidence presented. Market dynamics explain the potency increase adequately without requiring coordinated intent.
Higher potency means more danger: does not follow. Ignores dose titration in adult users. Potency alone does not establish proportional harm.

Thank you Dr. Yoho. I promise I did not read your excellent post prior to writing my four-part series “Ultraprocessed Cannabis: Potency, Policy, and Public Health in America.” The final post/podcast will drop Tuesday at https://www.eatinginamerica.co/p/ultraprocessed-cannabis-potency-policy!
We seem to be closely aligned on many points, including the potential for public health benefit with legalization and regulation at the federal level, the need for potency caps and standardization, that a copy of the tobacco/opioid/ultraprocessed food playbook has been passed to the cannabis industry, and the certainty that big money in cannabis will always prioritize profit over health.
And we tell the long story of cannabis in America in a similar way, although you brought many new facts and perspectives to me, and perhaps I have a few new angles for you and your readers! Also, I propose a number of recommended policy directions for us going forward. Would love your and your readers’ feedback!
I have a family member who needs to quit this Marijuana. how do they do that?
I think opiods should be available for extremely Chronic pain.
Alcoholic was the most toxic thing for me and I would rather be around someone who is a pot smoker than a drunk, but I choose neither uD83DuDE43 nor would you want to see me drunk on whiskey, I’m not a slobbering drunk, just mean as a rattlesnake. I don’t even like me drunk. I haven’t gotten in that shape for a very many years. Praise God uD83DuDC4F
Is there a pill to take to stop vaping..
