The Concord Prison Experiment Experiment Follow-Up

Investigator: Rick Doblin, Ph.D.

This study, originally published in the Journal of Psychoactive Drugs [Oct-Dec 1998] is one in a series of long-term follow-ups to early psychedelic research that MAPS has sponsored. The original 1961-63 Harvard study lead by Dr. Timothy Leary investigated the utility of psilocybin in reducing rates of recidivism for prisoners.
