There are a number of support groups across the United States that help people struggling with narcotics addiction to remain sober and healthy. The most well-known self-help groups are those affiliated with Alcoholics Anonymous (AA), Narcotics Anonymous (NA), and Cocaine Anonymous (CA), all of which are based on the 12-step model. Support groups for family members of people with addictions, like Al-anon or Alateen, can also be helpful.
