On this week's episode, Marc is in conversation with professor of neuroscience and psychology at Columbia University, Dr. Carl Hart; discussing his book "Drug Use for Grown-Ups: Chasing Liberty in the Land of Fear". Dr. Hart discusses his views on drug use and liberty; and explains why they don't go hand and hand. He is transparent about his personal drug use, and shares his beliefs on why we should consider revising our view on illegal drug use in the US.
