Professor David Nutt has spent a career making the argument for a rational, evidence-based approach to drug policy and drug use. The scientific evidence still challenges perceived wisdom on drugs and for that reason can appear to be contentious. In this podcast, the Professor explores the actual harms and potential benefits of various drugs, challenging myths surrounding classification and legislation, and exploring the societal impact of poorly informed drug policy. Using evidence in public policy should not be controversial. A podcast for anyone interested in understanding the scientific truth about drugs, free from political or moral concern.
