Stanton Peele, Ph.D. has been at the cutting edge in addiction theory and treatment and drug policy for fifty years. His seminal work began with his 1975 book, Love and Addiction (with Archie Brodsky), and extends to his 15th book, his 2021 memoir, A Life on the Scientific Edge: My Quest to Change How We See Addiction. On this journey, he has pioneered — with hundreds of articles, workshops, blogposts, and podcasts — the ideas that addiction includes more than substances, and of natural recovery, harm reduction, attacking addiction through real-world changes, and drug use as normal behaviour and natural life evolution rather than being a “disease.” He is still “on the edge.”
