Polydrug use among urban adolescent cigarette smokers.
Adolescent smokers are at increased risk for polydrug use, which is associated with more consequences than use of a single drug. Here we classified subgroups of polydrug use among urban adolescent cigarette-smokers described the sociodemographic, smoking, and depression correlates and identified three-year outcomes associated with subgroup membership. Adolescent cigarette smokers (N176 M Almost all participants (96%) reported using, on average, two (SD0.97) substances (including other tobacco products) in addition to cigarettes. Latent class analysis revealed two distinct classes of polydrug users. Limited Range Use (84%) class members reported current use of other tobacco, alcohol, and marijuana, as did Extended Range Use class members (16%) who also reported current use of harder drugs (i.e., cocainecrack, hallucinogens, ecstasy, and misused prescriptions). The classes did not differ on demographics or baseline likelihood of marijuana (χ Adolescent cigarette-smokers who reported extended range use (18%) also reported symptoms of clinical depression at baseline and follow-up. These findings indicate a need for early monitoring of depression symptoms and prevention and cessation interventions targeting this high-risk group.
