Socioenvironmental Risk Factors for Adolescent Marijuana Use in a United States-Mexico Border Community

Purpose: We examined how socioenvironmental risk factors unique to the United States-Mexico border, defined as border community and immigration stress, normalization of drug trafficking, and perceived disordered neighborhood stress, contribute to tobacco, alcohol, and marijuana use among adolescents residing there. Design: Cross-sectional design. Setting: The study was conducted at a high school on the United States-Mexico border. Subjects: A sample of 445 primarily Hispanic students (ages 14-18). Measure: Perceived Disordered Neighborhood Stress Scale, Border Community and Immigration Stress Scale, and Normalization of Drug Trafficking Scale. Analysis: Logistic regression assessed the association between the socioenvironmental risk factors and past 30-day tobacco, alcohol, and marijuana use. Results: Participants with higher border community and immigration stress scores were significantly more likely to have used tobacco (adjusted odds ratio [aOR] = 1.41, P < .01) and alcohol (aOR = 1.31, P < .01) in the past 30 days. Perceived disordered neighborhood stress also was associated with past 30-day alcohol use (aOR = 1.46, P < .00). The normalization of drug trafficking was associated with past 30-day marijuana use (aOR = 1.45, P < .05). Conclusions: Public health practitioners, educational institutions, and policy makers should consider the economic and normative environment of the United States-Mexico border for future substance use prevention and risk reduction efforts targeting border adolescents.
