Polysubstance use

Transitions in the Use of Multiple Substances 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).

Do Classes of Polysubstance Use in Adolescence Differentiate Growth in Substances Used in the Transition to Young Adulthood?

The current study estimates classes of polysubstance use in a large group of adolescents (ages 12–18 at baseline) and examines the longitudinal trajectories of cigarette, alcohol, marijuana, and illicit drug use from adolescence to young adulthood for each class.
