title: Sexual risk behavior associated with co-administration of methamphetamine and other drugs in a sample of HIV-positive men who have sex with men.
abstract: This study examined the association between sexual risk behavior and co-administration of methamphetamine with other drugs in a sample of 341 HIV-positive MSM. Those who reported methamphetamine co-administration in the past two months (65%) reported significantly more unprotected anal and oral sex and a greater number of casual, anonymous, and paid sex partners in this timeframe compared to men who used methamphetamine alone. Two primary patterns of co-administration were identified: 1) drug combinations motivated by sexual performance and enhancement (eg, methamphetamine, poppers, sildenafil); and 2) "party drug" combinations (eg, methamphetamine, GHB, ketamine). Implications for further research and possible applications to risk-reduction interventions are discussed.
