The purpose of this study is to evaluate whether a specially developed group counseling approach is better able to help HIV-positive gay and bisexual men (GBM) who use crystal meth to stop using methamphetamines, reduce sexual risk behaviors, and stay on their HIV medications than a standard drug treatment program. Another purpose is to determine whether having a drug abuse treatment program in an HIV medical clinic makes it easier to attend treatment than going to a separate location for drug abuse treatment.
