He has published over 175 papers and book chapters on the neurobiology and treatment of addiction and is Editor-in-Chief of The American Journal of Drug and Alcohol Abuse. In his semi-retired status, he is evolving from focusing on the consequences of substance use itself to the consequences of the drug war.

I feel they cause much more devastating effects physically. We need to lift the prohibition on marijuana.”

Published in 1971, Marihuana Reconsidered is the culmination of his early research, securing his place in history as a pioneer of the legalization movement. Since 1967, Dr. Grinspoon has grown to become one of the world’s most authoritative experts on cannabis.

He was a paratrooper in the U.S. Army’s 82nd Airborne Division, serving as the U.S. military’s first African-American officer in command of white troops. After an injury that led to his retirement from the military, and unable to gain entry to racially exclusive American medical schools, Dr. Primm received his MD from the University of Geneva in Switzerland. Despite the institutional and societal racism he faced as a young black physician in the late 1950s, Dr. Primm completed a residency in anesthesia in New York City, receiving awards for his performance and service. Working in underserved communities, he quickly observed how the misuse of narcotics was directly and indirectly responsible for a range of medical problems. In 1969, his interest in addiction and frustration with poor access to care led Dr. Primm to help create the Addiction Research Treatment Corporation (ARTC), where he served as the executive director for decades.
