Substance use patterns in 9 to 13-year-olds: Longitudinal findings from the Adolescent Brain Cognitive Development (ABCD) study

Abstract The ABCD Substance Use Workgroup describes substance use patterns within the cohort. The ABCD cohort is entering adolescence and initiating substance use. By ages 12–13, nearly 40% report lifetime substance experimentation and/or use. Nearly 7.5% also reported lifetime substance use (>experimentation). Sociodemographic and parental substance problems remain as predictors of initiation.
