Study Limitations: Study Limitations Results are only representative of young MSM who attended public venues in the 7 urban areas Data were available on drug/alcohol use and sexual behaviors in the last 6 months, but not on drug/alcohol use at the time of specific sexual encounters This analysis does not address risks of being high during sex on drugs other than meth


Conclusions: Conclusions Among YMS participants in 7 urban areas: Sex under the influence of drugs or alcohol was common Meth use and being high on meth during sex was more common in WCC than ESC Being high on meth during sex was associa- ted with a greater no. of male sex partners, male exchange partners, and unprotected sex with both males and females


Implications: Implications HIV and STD prevention efforts should emphasize meth use in discussions of drug use and its consequences, particularly among young MSM on the West Coast Further studies should examine the relative risk of meth use vs other drug use and ways to effectively prevent, discontinue, or manage meth use to reduce associated risky sexual practices
