PROGRESSIONS OF ALCOHOL, CIGARETTE, AND MARIJUANA USE IN ADOLESCENCE

This study examined the progressive relations among adolescent use of alcohol, cigarettes and marijuana using latent growth curve analyses. Specifically, the present study examined three models to determine (1) the effect of prior cigarette use on alcohol use and development and the relationship between change in cigarette use and the development o f alcohol use (N = 115), (2) the effect of prior alcohol use on cigare tte use and development and the relationship between change in alcohol use and the development of cigarette use (N = 199); and (3) the effec t of prior alcohol and cigarette use on marijuana use and development, and the relationship between change in alcohol use and cigarette use and the development, of marijuana use (N = 287). Support was found for the relation between prior levels of substance use and involvement in other substances. Cigarette use, in particular, was particularly impo rtant in the subsequent involvement of alcohol and marijuana.
