title: Typology of club drug use among young adults recruited using time-space sampling.
abstract: The present study examined patterns of recent club drug use among 400 young adults (18-29) recruited using time-space sampling in NYC. Subjects had used at least one of six club drugs (methylenedioxymethamphetamine (MDMA), ketamine, gamma-hydroxybutyrate (GHB), cocaine, methamphetamine, and D-lysergic acid diethylamide (LSD)) within the prior 3 months. We used latent class analysis (LCA) to estimate latent groups based on patterns of recent club drug use and examined differences in demographic and psychological variables by class. A 3-class model fit the data best. Patterns were: Primary cocaine users (42% of sample), Mainstream users (44% of sample), and Wide-range users (14% of sample). Those most likely to be Primary cocaine users were significantly less likely to be heterosexual males and had higher educational attainment than the other two classes. Those most likely to be Wide-range users were less likely to be heterosexual females, more likely to be gay/bisexual males, dependent on club drugs, had significantly greater drug and sexual sensation seeking, and were more likely to use when experiencing physical discomfort or pleasant times with others compared to the other two groups. Findings highlight the utility of using person-centered approaches to understand patterns of substance use, as well as highlight several patterns of club drug use among young adults.
