Marc Lewis, Ph.D.

Marc Lewis, Ph.D. is a developmental neuroscientist and professor of developmental psychology, recently at the University of Toronto, where he taught and conducted research from 1989 to 2010, and presently at Radboud University in the Netherlands. He is the author or co-author of over 50 journal publications in psychology and neuroscience. Marc experimented with a large variety of drugs in his youth, eventually becoming addicted to opiates. His addiction cost him several close relationships and led him into trouble with the police. At the age of 30, he quit drugs for good, then reentered grad school and received his Ph.D. five years later. Around 2006, Marc's research led him back to addiction, this time as a neuroscientist studying the brain changes that amplify craving and weaken self-control.

His recent book, Memoirs of an Addicted Brain, blends his life story with a user-friendly account of how drugs affect the brain and how addiction seriously alters neural chemistry and structure. From the back cover: "An engrossing and vividly written swirl of raw personal drama, themes of despair, loss and triumph, brilliantly rendered brain science, and clear thinking on the experience and essence of addiction. Illuminating even to experts, accessible to all." Gabor Maté, MD, author of In the Realm of Hungry Ghosts: Close Encounters With Addiction. His upcoming book is The Biology of Desire: Why Addiction is Not a Disease. It combines neuroscientific findings with intimate biographies of recovered addicts, to make the case that addiction develops through accelerated learning. From the back cover: “This is the real story of ‘this is your brain on drugs,’ but one that provides a refreshing, convincing alternative to the widespread disease-model view of addiction. . . . It offers far more positivity about ways out of addiction than those offered by traditional treatment approaches, providing hope for those struggling and their loved ones.” —Anne M. Fletcher, MS, author of New York Times bestselling Sober for Good, Inside Rehab, and the Thin for Life books
