This study adds to the literature by examining the extent to which school, employment, and romantic relationship factors can disrupt problematic patterns of substance use (i.e. polysubstance use) in a sample of youth followed a decade from adolescence (ages 12-18) to young adulthood (ages 22-29). Specifically, we examine the extent to which school, employment, and romantic relationship factors can disrupt transitions among high-risk use classes at various developmental time points in the transition from adolescence to young adulthood.
In this study, we add to this literature by examining transitions among classes of four substances (i.e., cigarettes, binge drinking, marijuana, and illicit drugs) in a large sample followed for a decade from adolescence (ages 12–18) to young adulthood (ages 22–28).
