The experiment was conducted between 1961–1963 in Concord State Prison, a maximum-security prison for young offenders, in Concord, MA by a team of Harvard University researchers under the direction of Timothy Leary, which included Michael Hollingshead, Dr. Allan Cohen, Dr. Alfred Alschuder, Dr. George Litwin, Dr. Ralph Metzner, Dr. Gunther Weil, and Dr. Ralph Schwitzgebel, with Dr. Madison Presnell as the medical and psychiatric adviser. The original study involved the administration of psilocybin to assist group psychotherapy for 32 prisoners in an effort to reduce recidivism rates. Results Records at Concord State Prison suggested that 64 percent of the 32 subjects would return to prison within six months after parole. However, after six months, 25 per cent of those on parole had returned, six for technical parole violations and two for new offenses. Few short-term projects with prisoners have been effective to even a minor degree.[citation needed] In addition, the personality test scores indicated a measurable positive change when pre-psilocybin and post-psilocybin results were compared.[citation needed] en.wikipedia.org/wiki/Concord_Prison_Experiment
