"While Alcoholics Anonymous (AA) has existed for more than 70 years, and is the most commonly sought source of help for alcohol-related problems in the United States, there is little “hard scientific evidence” showing that AA and Narcotics Anonymous (NA) can improve substance-use outcomes. This study examined how helpful AA and NA may be for adolescents, finding long-term benefits even though many youth discontinue attendance after time."
