Episode 1593: Dr. Carl Hart | The Brogan Report

Introduction

Episode 1593, featuring Dr. Carl Hart, aired on January 12, 2021. Dr. Hart is a professor of psychology and psychiatry at Columbia University and a legitimate neuroscientist with decades of research on the behavioral effects of psychoactive drugs. However, in this episode — recorded to promote his book Drug Use for Grown-Ups: Chasing Liberty in the Land of Fear — Hart made a series of claims that downplay the dangers of heroin and methamphetamine use, minimize addiction risks, and dismiss the severity of the opioid crisis. Most troublingly, Joe Rogan agreed on air to try heroin and cocaine with Hart, lending enormous validation to dangerous drug experimentation.

TL;DR: A credentialed neuroscientist used his expertise to minimize the well-documented dangers of heroin and methamphetamine, dismiss addiction as rare, and characterize the opioid crisis as a problem of “ignorance” rather than drug toxicity. Rogan was not only uncritical but actively enthusiastic, agreeing to try heroin and cocaine on air. This episode aired during the worst year of drug overdose deaths in U.S. history.

Who is Dr. Carl Hart?

Dr. Carl Hart holds genuine credentials:

Mamie Phipps Clark Professor of Psychology (in Psychiatry) at Columbia University
First tenured African-American professor of sciences at Columbia (2009)
PhD in neuroscience; over 25 years of research on psychoactive drugs
Author of High Price (2013) and Drug Use for Grown-Ups (2021)
Publicly admitted to recreational use of heroin, cocaine, methamphetamine, and other drugs

Hart’s credentials make his claims more dangerous, not less. When a Columbia professor tells millions of listeners that heroin use is comparable to alcohol and helps him “maintain work-life balance,” that carries enormous weight — even when the claims conflict with mainstream addiction science and epidemiological data.

Problem 1: Minimizing Heroin Addiction Risk

Claim: Hart argued that most people who use heroin do not become addicted, comparing heroin withdrawal to having the flu and characterizing heroin use as no more problematic than alcohol consumption.

What the Evidence Actually Shows

The study Hart himself cites acknowledges that 20-40% of first-time heroin users become addicted — hardly the negligible risk he implies (City Journal review)
The National Institute on Drug Abuse reports that about 23% of people who use heroin develop opioid use disorder, a rate dramatically higher than most other substances (NIDA)
Hart’s comparison of heroin withdrawal to the flu dangerously understates withdrawal severity. Medical literature documents that opioid withdrawal can include severe dehydration, cardiac complications, and in some cases can be life-threatening, particularly without medical supervision (NCBI)
Hart’s characterization relies on his own anecdotal experience with “small, controlled doses of extended-release morphine” — a fundamentally different scenario from how most people encounter heroin on the street, where potency is unpredictable and fentanyl contamination is rampant

Why This Matters

A 20-40% addiction rate means that for every 5 people who try heroin based on Hart’s reassurances, 1 to 2 of them will develop a substance use disorder. Framing this as a negligible risk is irresponsible, especially on a platform reaching millions.

Problem 2: Downplaying Methamphetamine Neurotoxicity

Claim: Hart argued that methamphetamine does not cause significant brain damage and that claims about “meth mouth” and cognitive impairment are exaggerated or fictional.

What the Science Actually Shows

A landmark 2004 study published in the Journal of Neuroscience found that methamphetamine abusers had 7.8% smaller hippocampal volumes than control subjects (p < 0.01), with deficits correlated with impaired memory performance (Thompson et al., 2004)
Extensive peer-reviewed research demonstrates that methamphetamine produces neurotoxicity through multiple pathways: oxidative stress, neuroinflammation, dopaminergic neuron damage, and apoptosis (PMC review)
Postmortem analysis of human brain tissue confirms chronic methamphetamine use produces neurotoxic changes in the hippocampus, cortex, and striatum (PMC)
Regarding “meth mouth,” the American Dental Association has documented the condition extensively, and a 2015 study in the Journal of the American Dental Association found methamphetamine users had significantly higher rates of tooth decay, missing teeth, and gum disease (JADA, 2015)

Hart’s claim that meth-related brain damage is “probably more fiction than fact” directly contradicts a robust body of neuroimaging and postmortem evidence.

Problem 3: Dismissing the Opioid Crisis

Claim: Hart characterized the opioid epidemic as primarily a problem of “ignorance” rather than drug toxicity, writing that “people are not dying because of opioids, they are dying of ignorance.”

What the Data Actually Shows

In 2020, the year Hart’s book was being promoted, over 93,000 Americans died from drug overdoses — the highest number ever recorded at that time (CDC)
By 2021, that number surged to 106,699 deaths, with synthetic opioids (primarily illicitly manufactured fentanyl) driving the increase (CDC NCHS)
The overwhelming majority of these deaths involved fentanyl contamination of the drug supply — something individual “responsibility” or “education” cannot adequately address when users cannot know the potency or composition of what they are consuming
Hart’s framing that drug users simply need to be more “grown-up” about their use ignores the fundamental reality that the unregulated drug supply is inherently unpredictable, making even “responsible” use dangerous

Expert Criticism

The Los Angeles Review of Books criticized Hart’s approach as “good drug policy based on bad rhetoric,” noting his tendency to cherry-pick evidence and center his own anecdotal experience while dismissing the experiences of addiction sufferers (LARB).

The City Journal review noted that Hart “offers thin evidence for his case” and that “it does not require deep research to rebut Hart’s denialism” given the scale of overdose deaths (City Journal).

Problem 4: Joe Rogan Agrees to Try Heroin and Cocaine

Perhaps the most alarming moment in the episode was when Rogan agreed, on multiple occasions, to try heroin and cocaine with Hart under supposedly controlled conditions. This was not idle banter — it was a genuine expression of willingness on a show heard by millions.

Why This Is Dangerous

Rogan’s agreement lends enormous social validation to trying hard drugs. When one of the world’s most popular podcast hosts says he is willing to try heroin, it normalizes experimentation for his massive audience
The framing of “controlled circumstances” with a professor creates a false sense of safety that most listeners cannot replicate
This aired during a period when the U.S. was experiencing the deadliest year of drug overdoses in history, making casual discussions of heroin experimentation particularly reckless

Rogan’s Role

Rogan failed in every respect as an interviewer on this episode:

He did not push back on Hart’s minimization of addiction risks
He did not cite any of the extensive literature contradicting Hart’s claims about meth brain damage or heroin addiction rates
He actively validated Hart’s framing by expressing enthusiasm about trying heroin and cocaine
He did not mention the ongoing opioid crisis or the record-breaking overdose death toll
He treated Hart’s credentials as a blanket endorsement of all his claims, failing to recognize that even credentialed experts can be wrong — especially when their claims contradict the broader scientific consensus

What Hart Gets Right (And Where It Goes Wrong)

It is important to acknowledge that some of Hart’s underlying arguments have merit:

Drug decriminalization has strong evidence supporting it (Portugal’s model has shown positive outcomes)
The War on Drugs has caused enormous harm, particularly to Black communities
Drug policy should be evidence-based rather than driven by moral panic
Addiction is not inevitable for all users of any substance

However, these valid points are fatally undermined by Hart’s tendency to:

Overstate safety: Moving from “not everyone becomes addicted” to “heroin is basically fine” is a dangerous leap
Cherry-pick evidence: Citing only research that supports his thesis while dismissing contradictory findings
Center personal anecdote: His own experience with controlled doses in a safe environment tells us nothing about the risks facing typical users buying street drugs
Ignore context: Promoting casual heroin use during the worst overdose crisis in American history shows a troubling disconnect from public health reality

Real-World Harm

The episode aired in January 2021, during a period when drug overdose deaths were increasing 30% year-over-year
Hart’s claims reached millions of listeners through a platform with minimal fact-checking infrastructure
The normalization of heroin and methamphetamine use by a Columbia professor, validated by the world’s most popular podcaster, has the potential to influence vulnerable individuals — particularly young men, who make up both Rogan’s core audience and a disproportionate share of overdose deaths
Multiple addiction medicine professionals and public health experts have criticized Hart’s public messaging as dangerous (Columbia Magazine)

Conclusion

This episode exemplifies a recurring problem on JRE: a credentialed expert using legitimate grievances about drug policy (the War on Drugs, racial disparities in enforcement, criminalization of addiction) as a Trojan horse for dangerously misleading claims about drug safety. Hart’s real credentials make his misinformation more persuasive, not less. And Rogan’s complete failure to challenge any of these claims — combined with his enthusiastic agreement to try heroin — transformed what could have been a nuanced drug policy discussion into a three-hour infomercial for recreational hard drug use, airing at the peak of America’s overdose crisis.
