Ayahuasca-Assisted Treatment for Addiction (British Columbia, Canada)

Ayahuasca-Assisted Treatment for Addiction (British Columbia, Canada)

Principal Investigator: Gerald Thomas, Ph.D.
Study Site: British Columbia, Canada

This study has been completed

Sponsored by MAPS Canada, this observational study investigated the safety and long-term effectiveness of ayahuasca treatment for individuals suffering from addiction and dependence. Combining Western psychotherapeutic techniques with South American shamanic (Vegetalista) healing practices, this study gathered preliminary evidence about the safety and effectiveness of ayahuasca-assisted therapy.

Treatment consisted of participation in a five-day retreat (facilitated by independent psychiatrist Gabor Maté, M.D.) including ayahuasca-assisted therapy, which may help reduce problematic substance use as well as addictions, compulsive behavior, and self-harming thought patterns.

This study was conducted in cooperation with a British Columbia First Nations band. The results were published in 2013 in the peer-reviewed journal Current Drug Abuse Reviews.

Kenneth Tupper, Ph.D, Co-Investigator

Kenneth Tupper is an Adjunct Professor at the School of Population and Public Health at the University of British Columbia, where his research interests include the cross-cultural and historical uses of psychoactive substances; public, professional and school-based drug education; and creating healthy public policy to maximize benefits and minimize harms from currently illegal drugs. Kenneth is also a member of the Advisory Board of the Multidisciplinary Association for Psychedelic Studies (MAPS) Canada, and has been active in the field of psychedelic studies for more than fourteen years. His Ph.D. dissertation (and earlier M.A. thesis) in Education developed the concept of “entheogenic education,” a theoretical frame for understanding how psychedelic plants and substances—in particular the Amazonian brew ayahuasca—can function as cognitive tools for learning.
