Adolescent Pathways to Adult Smoking: Ethnic Identity, Peer Substance Use, and Antisocial Behavior.

SMOKING; TOBACCO use; ETHNICITY; DELINQUENT behavior; SUBSTANCE abuse

African-Americans and Puerto Ricans were interviewed during adolescence, in their early twenties, and then again in their mid-twenties. Results indicated that earlier adolescent smoking, family conflict, and weak ethnic identity were significantly related to antisocial behavior, which in turn was related to associating with friends who smoked and/or used illegal drugs, and ultimately, to their own smoking. Results further indicate that early interventions in the development of tobacco use should focus on decreasing parental and adolescent smoking and parent–child conflict. If intervention occurs at a later time point, the emphasis should be on increasing ethnic identity and decreasing antisocial behavior. [ABSTRACT FROM AUTHOR]
