Dr. Carl L. Hart, Ziff Professor at Columbia University and former chair of the Department of Psychology, is one of the world’s preeminent experts on the effects of so-called recreational drugs on the human mind and body. Dr. Hart is open about the fact that he uses drugs himself, in a happy balance with the rest of his full and productive life as a colleague, husband, father, and friend. In Drug Use for Grown-Ups, he draws on decades of research and his own personal experience to argue definitively that the criminalization and demonization of drug use–not drugs themselves–have been a tremendous scourge on America, not least in reinforcing this country’s enduring structural racism.
