Drug use and sexual risk among gay and bisexual men who frequent party venues.

Research connecting club drug use to risky sex among gay/bisexual men (GBM) contains methodological issues that have limited knowledge about the relative risks of distinct drugs. This paper reports drug use and sexual behavior data from 197 GBM who frequented at least one party venue within 3 months of participating. Alarming rates of drug use and unprotected anal intercourse (UAI) with casual sex-partners were reported in connection with time spent at a bar, club or circuit party. Structural equation modeling revealed that use of methamphetamine, gammahydroxybutrate (GHB), and/or ketamine (K), but not use of ecstasy, at a party venue helped explain likelihood of UAI with a casual sex-partner while under the influence of a drug during/following time partying (β = 0.41, p < .01). Findings suggest use of methamphetamine, GHB and/or K at party venues increases risk for subsequent UAI with casual sex-partners. Study implications, limitations, and recommendations for future research are discussed.
