This protocol will evaluate the degree to which a combined group and individual intervention that also uses recovery mentors, "Stimulant Abuser Groups to Engage in 12-Step" (STAGE-12), improves substance-related outcomes compared to treatment as usual (TAU) without STAGE-12 among stimulant (methamphetamine and/or cocaine) abusers. The primary objective of the protocol is to evaluate reduction in percent of days of stimulant use. Secondary objectives include evaluating reduction in percent days of use of other substances, the degree to which STAGE-12 increases involvement in 12-step activities and attendance at 12-step meetings, and the extent to which such 12-step involvement and meeting attendance influences substance use outcomes.
