This study examined the use of five party drugs popular among many gay and bisexual men: ketamine, methylenedioxymethamphetamine (ecstasy), crystal methamphetamine (Tina, crystal, ice) cocaine, and gamma-hydroxybutyrate (GHB). Investigators sought to understand how social contexts of party drug use interact with men's psychological factors to influence sexual risk-taking. As drug use patterns change over time, BUMPS followed 450 men for one-year to study how their drug use evolved. The project recruited participants from gay clubs, bars, public sex environments, community agencies, and Internet chat rooms.
