Background Adolescence is a pivotal life stage marked by educational advancement, entry into the workforce and formation of lasting relationships. Globally, adolescence is also the peak period during which individuals first engage in alcohol and/or drug consumption. This scoping review aimed to summarize existing longitudinal research on factors and outcomes related to adolescent substance use to identify gaps in existing evidence.

Conclusions The body of longitudinal evidence on adolescent substance use is rapidly expanding yet significant research gaps exist. Rising levels of cocaine use and its substantial health impacts motivate further research on all potentially important factors associated with cocaine use to guide interventions for prevention and treatment.
