Today we welcome Carl Hart. He is the Ziff Professor of Psychology in the Departments of Psychology and Psychiatry at Columbia University. He is known for his research on neuropsychopharmacology and his advocacy for the decriminalization of recreational drugs. Carl is the author of High Price and has co-authored the introductory textbook Drugs, Society, and Human Behavior with Charles Ksir. His most recent book is called Drug Use for Grown-Ups.In this episode, I talk to Carl Hart about drug use and addiction. Society is quick to judge all drug users as addicts but Carl’s research found that the majority of drug users do not meet the criteria for pathology. Recreational drugs, when used responsibly, can have positive effects on people.  Instead of waging a war on drugs, Carl advocates for laws that better regulate the production and sale of substances. We also touch on the topics of health, law, racism, cognition, and sociology.Website: drcarlhart.comTwitter: @drcarlhart Topics02:32 Carl’s interest in neuropsychopharmacology06:12 The brain disease model of addiction11:22 Should we talk about drugs with kids?13:47 Responsible drug use for grown-ups17:08 Drugs in pursuit of happiness22:54 The Harrison Narcotics Tax Act 29:28 Scott’s experience with edibles33:21 Why we need drug checking facilities37:01 The drug user tropes in media 41:59 Predictors of drug abuse and addiction 46:42 Drug overdose and safety50:09 Personal responsibility in drug addiction52:45 Our moralism is killing us55:06 Coming out as a heroin user57:52 Bob Marley and James Baldwin
