His work focused on the effects of psychedelics, primarily LSD. Cohen published 13 books in his life, all of them based on drugs and substance abuse. He began working with LSD in the 1950s. One of his earlier works is a video of an experiment that shows Cohen interviewing a woman before and after administering her LSD. In the later part of the 1960s he worked as a director for the National Institute of Mental Health in their Division of Narcotic Addiction and Drug Abuse.
