This study utilized qualitative content analysis to examine messages conveyed about alcohol and other drugs by urban Black mothers ( N = 130) with a personal, familial, or personal and familial history of problematic substance use to younger and older adolescents ( M = 15.2 years). Data from a two‐cohort longitudinal sample revealed considerable similarity in themes across the younger and older cohorts. Results suggest Black mothers offer more messages of information and advice to younger adolescents, while communicating directives related to use to older adolescents.
