Five million people participate in self-help groups each year: An annual average of five million persons aged 12 and older attended a self-help group in the past year because of their use of alcohol or illicit drugs: 45% attended because of their alcohol use only, 22% attended because of their illicit drug use only, and 33% attended because of their use of both alcohol and illicit drugs. The data also indicate that 45% of past-year self-help group participants—or 2.3 million individuals—were able to abstain from use of these substances in the past month. These findings are presented in a report, Participation in Self-Help Groups for Alcohol and Illicit Drug Use: 2006 and 2007, which is based on data from the National Survey on Drug Use and Health (NSDUH), an annual survey of 67,500 respondents. The data also indicated that 33% of those who attended a self-help group during the past year also received specialty treatment for substance abuse in the past year. The report is available on the Web site of SAMHSA's Office of Applied Studies at drugabusestatistics.samhsa.gov.
