Carl Hart is the Ziff Professor of Psychology at Columbia University and an expert on substance abuse and addiction. He has spent much of his career studying the interaction of the environmental, neurobiological and psychological factors that influence human behavior. He is interested in the factors that mediate drug self-administration behavior, and in developing more-humane drug policies.

Hart’s 2021 book, Drug Use for Grown-Ups: Chasing Liberty in the Land of Fear, examines the positive effects of drug use and the negative effects of the war on drugs. His 2013 book, High Price, blends personal narrative with years of research on drugs and psychology and challenges traditional assumptions of substance abuse.

In addition to his academic work, Hart has served on the National Advisory Council on Drug Abuse and  on the board of directors of the Drug Policy Alliance.
