Much of the existing risk factor literature focuses on identifying predictors of low levels of substance use versus higher-levels of substance use. In this article, we explore more nuanced patterns of alcohol, tobacco and other drug (ATOD) use during late adolescence.
Our aims were to: (1) identify subgroups of youth with qualitatively different patterns of ATOD use and (2) explore whether membership among qualitatively distinct, high-risk classes could be predicted based on early adolescent risk factors.
Data came from a selected subsample of the National Longitudinal Survey of Youth (n = 1689). Predictors were measured when youth were about 12 years old; ATOD use was assessed when youth were aged 17 years.
Results showed that adolescent ATOD use is not a homogenous behavior. Four distinct classes of adolescent ATOD users were derived. Each class had a qualitatively distinct and discriminable pattern of ATOD use. Ecological predictors were shown to differentiate between latent classes, with peer factors playing a particularly important role in differentiating between high-risk and higher-risk users.
Implications for prevention and limitations are discussed.
