There are several options for treating substance abuse. Treatment programs aim to reduce drug use and criminal behavior while improving employment and health. The most common treatments include outpatient counseling, methadone maintenance for opioid addiction, therapeutic communities, and self-help groups like Alcoholics Anonymous and Narcotics Anonymous. Longer treatment programs lasting three months or more tend to be most effective. While treatment shows benefits, challenges remain around access, cost, relapse, and community acceptance of treatment centers.
