Dr. Carl Hart is a neuroscientist and psychologist at Columbia University whose research focuses on the effects of psychoactive drugs on the brain.   He’ll talk about his positions on recreational drug use, which continue to spark controversy and are often at odds with others in his field. Hart’s latest book, Drug Use for Grown-Ups: Chasing Liberty in the Land of Fear, draws on decades of research and his own personal experience to argue that the criminalization and demonization of drug use, rather than drugs themselves, has been a scourge on America and reinforced this country’s enduring structural racism.  Hart is also the author of High Price, and co-author of the textbook Drugs, Society and Human Behavior.  On January 27, 2021, Carl Hart spoke with Lara Bazelon, a professor of law at the University of San Francisco.
