Marijuana Anonymous (MA) formed in June 1989 to address compulsive use of cannabis. Since its inception, MA has followed the Twelve Traditions and suggests practicing the Twelve Steps, which both originated from AA. Among the founders at the first MA conference in Morro Bay were delegates from Marijuana Smokers Anonymous (Orange County, California), Marijuana Addicts Anonymous (the San Francisco Bay area), and Marijuana Anonymous (Los Angeles County). Other existing fellowships from Seattle and New York enfolded into MA later.
Meetings are a vital part of the MA program. This is where fellowship members go for support, for literature, and mark and celebrate their abstinence from marijuana.
Various meeting formats exist. These include, but are not limited to: speaker, participation, book study, candle light.
