12-Step Meetings May Help Teens Beat Alcohol, Drug Abuse. Programs such as Alcoholics Anonymous seem to work as well in teens as in adults, study finds. Teens undergoing treatment for alcohol or drug abuse can benefit from the 12-step program used by groups such as Alcoholics Anonymous (AA) and Narcotics Anonymous (NA), researchers say. While these programs are widely available, little research has looked at how effective they are for teens. The new study included 127 teen substance abuse-treatment outpatients (95 males, 32 females, aged 14 to 19) who were assessed when they began treatment and three, six and 12 months later. The findings are published online and in the July print issue of the journal Alcoholism: Clinical & Experimental Research.
