How school discrimination and isolation drive teen substance use

This study examines how school belonging and experiences of racial mistreatment influence substance use patterns among U.S. high school students, including cannabis. The research recognizes that substance use doesn't occur in a vacuum—social factors like feeling connected to school and facing discrimination play important roles in whether teens use cannabis, alcohol, and e-cigarettes. By studying the intersection of these social experiences, researchers aimed to identify which students might be at higher risk for substance use and understand the underlying mechanisms driving these behaviors.

The findings highlight that perceived racial mistreatment and weak school belonging are significant risk factors associated with increased cannabis and other substance use among high school students. Students who experience racial discrimination or feel disconnected from their school community show elevated rates of substance use, suggesting that social marginalization and isolation contribute to higher risk behaviors. This connection is particularly important because it points to how systemic and interpersonal discrimination may inadvertently drive substance use among vulnerable youth populations.

These results have important implications for prevention and intervention strategies. Rather than focusing solely on drug education, schools should prioritize creating inclusive environments where all students feel valued and safe, particularly students of color who face additional stressors from racial mistreatment. By addressing the root causes of substance use—including discrimination and lack of belonging—schools can create more effective prevention programs that tackle both the psychological and social factors influencing teen cannabis and substance use.
