AA and NA Participation = 50% Less Substance Abuse

Male substance abuse patients (N=180, 82% African American, mostly low income) who participated in self-help groups (Alcoholics Anonymous, Narcotics Anonymous) after treatment significantly reduced their frequency of alcohol and cocaine use by the 7-month followup.

Participants with high self-help attendance rates used alcohol and/or cocaine less than half as much as did those with low self-help attendance.

This was true regardless of previous substance use and whether or not they completed a 4-week hospital rehabilitation program.

Hence, the effects of self-help groups were not simply due to motivation or other characteristics of the individuals who participated.
