A fellowship is a group of people who share common interests, goals, and ideals. In terms of alcoholism and drug abuse, a fellowship is a group of people living together in order to achieve a sober or drug-free lifestyle or a self-help group of people struggling with substance abuse that meets on a regular basis. Therapists in the field of substance abuse speak of “12-step fellowships” or groups that are based on the 12 founding principles of Alcoholics Anonymous. These groups support members in their common goal of becoming and remaining sober. Besides Alcoholics Anonymous, there are 12-step programs such as Narcotics Anonymous, Overeaters Anonymous, and ones with similar names for cocaine, methamphetamine, nicotine, gamblers, methadone, marijuana, kleptomania, sex addiction and many more. Sometimes after people complete residential treatment program for drug or alcohol abuse, they enter a fellowship with others in the same phase of recovery. They may live together in a “half-way house” or “sober-living facility” and help each other by encouraging sobriety and attending 12-step meetings together.
