Objective: The current study examined longitudinal associations between friend's substance use, friendship quality, parent-adolescent relationship quality, and subsequent substance use among an adult population. Design: Participants were 166 adolescents, their parents, and their close same-sex friends recruited from both urban and suburban high schools surrounding a large metropolitan area. Measures of relationship characteristics in the10th grade were used to predict concurrent substance use and changes in substance use over a 1-year period. Results: The most consistent predictor of the use of different substances and changes in substance use over time was the friend's substance-using behavior. Negative interpersonal interactions with a friend were related only to tobacco use, and friendship support neither contributed to nor protected against substance use. Mother-adolescent relationship support was associated with lower levels of concurrent substance use, as well as lower levels of hard drug use over time. Conclusions: Findings highlight the need to examine parents and peers simultaneously and the importance of parental relationships and peer behavior on adolescent substance use. Limitations and future directions are discussed.
