Cumulative Contextual Risk at Birth and Adolescent Substance Initiation: Peer Mediation Tests
Background: Children who experience multiple adversities, such as prenatal exposure to drugs and poverty, early in development are at increased risk for the early initiation of alcohol and cigarette use. However, studies that examine potentially malleable processes associated with substance use init...
