Distinct substance use patterns and risk of unintentional injury, violence, and mortality in adolescence: a latent class analysis and 8-year prospective cohort study of 68 301 students aged 15-19 years.

Previously, we identified distinct adolescent substance use patterns.

Here we characterized adolescents with distinct patterns of substance use and tested whether patterns were associated with acute outcomes.

Previously identified substance use patterns were Alcohol Only (48.8%), Frequent Binge Drinking (23.3%), Experimental Use (16.3%), and Early Multiple Use (11.6%).

Substance use patterns were associated with the risk of unintentional injury, violence, and mortality in a dose-dependent manner.
