Background and objective Findings from observational studies indicate that early drug use is a strong predictor of further drug abuse. Because competing explanations abound in cross-sectional studies, causal interpretations from these investigations pose considerable challenge. We evaluated the relationship between early drug use and progression, while estimating modifying influences of adolescents' social contexts. Method We applied a national longitudinal survey of 11,182 adolescents growing into adulthood over a 14-year period.
