Dr. Keith Humphreys, a Stanford psychiatrist and addiction researcher, discusses the science of addiction across substances and behaviors with Andrew Huberman. He defines addiction as the persistence of harmful behavior despite consequences, explains how genetic risk varies by substance (citing heritability estimates of 0.3–0.5), and clarifies that the only way to know a substance won't damage your life is to never use it. On alcohol, he dismantles the red wine heart-health myth, explaining that any cardiac benefit is outweighed by cancer risk. On cannabis, he notes that current products average 20% THC versus 5% in the 1980s, producing roughly 65 times the brain exposure when combined with daily use patterns.
Humphreys covers gambling's 'losses disguised as wins' mechanism, the 40-year failure to develop pharmacotherapy for stimulant addiction, and the Cochrane review showing AA outperforms cognitive behavioral therapy by 50% on abstinence outcomes. He discusses GLP-1 agonists as a potential tool for reducing alcohol and other substance cravings, and the emerging role of TMS for treatment-resistant depression. The episode closes with his reflections on hospice work and the connection between addiction and the fear of death.
Addiction Defined as Persistent Harminsight
Humphreys defines addiction not as compulsion or frequency but as the persistence of doing something harmful to the point of destruction, citing the classic rat brain-stimulation study.
Red Wine Myth and J-Curveinsight
Humphreys explains that the J-shaped curve showing non-drinkers with higher mortality is confounded by including former alcoholics in the non-drinking group, and that any cardiac benefit is smaller than the cancer risk.
Cannabis Potency 65x Higherdata
Humphreys compares 1980s cannabis at 3–5% THC used on weekends to current 20% THC used daily, calculating roughly 65 times the brain exposure, equivalent to the difference between coca leaf and cocaine.
Losses Disguised as Winsinsight
Humphreys explains the industry term LDWs, where slot machines present net losses as wins through celebratory sounds and animations, keeping players engaged while they lose money.
No Cocaine Drug in 40 Yearsdata
Humphreys calls the absence of any effective pharmacotherapy for stimulant addiction the biggest disappointment of his career, noting that contingency management (paying for clean urine tests) is the only proven intervention.
Humphreys describes the Cochrane Collaboration Review he co-authored showing AA and 12-step facilitation outperform CBT and motivational enhancement therapy by 50% on abstinence outcomes for alcohol.
GLP-1s May Reduce Cravingsstrategy
Humphreys describes how a friend on GLP-1s no longer thinks about food all day, and speculates that the same satiety mechanism could reduce alcohol and other substance cravings, with early data showing drops in alcohol use.
Addiction as Escape from Deathinsight
Huberman asks whether all addiction is an attempt to escape the fear of death. Humphreys agrees broadly, noting that heavy substance use often provides short-term oblivion from painful truths, and that recovery forces confrontation with those truths.
Dr. Keith Humphreys is a professor of psychiatry and behavioral sciences at Stanford School of Medicine and a leading expert on treating addictions, drug laws and policy. We discuss all the major addictive substances and behaviors, including alcohol, opioids, gambling, stimulants, nicotine, cannabis and more, focusing on how genetics and certain use patterns shape addiction susceptibility. We discuss the best evidence-based tools for recovery, from 12-step programs to emerging treatments such as psychedelics and ibogaine. Anyone interested in making better choices for their health and/or seeking to avoid or overcome addictions ought to benefit from this episode. Read the episode show notes at hubermanlab.com.
