Trauma and racial discrimination: examining their association with marijuana behaviors among black young adults

Indiana University-Purdue University Indianapolis (IUPUI)Marijuana use has been shown to increase and peak during young adulthood (i.e., ages 18-35). However, it appears that Black individuals do not decline in use at rates similar to other race groups. Marijuana use among Black adults has been linked to more problems such as increased arrests, greater mental health disorder diagnoses, and substance dependence. The biopsychosocial model of racism and race-based theoretical framework aims to understand how factors such as racial discrimination as a traumatic event could be associated with marijuana behaviors, particularly among Black adults. The present study aims to examine the association between racial discrimination and marijuana use and problem use above and beyond trauma exposure. Further, I aimed to explore whether gender or vocation (college, community, and military) moderated the relationships. 391 Black adults (57.5% female; mean age 24.9) completed measures on marijuana use and problems, trauma exposure, and racial discrimination distress. Hierarchical linear regression and Hayes PROCESS macro were used to evaluate the study aims. Racial discrimination distress was associated with marijuana use above and beyond trauma exposure (R2=.016, p=.004). However, racial discrimination distress did not add significant variance within the model for problem marijuana use (R2=.001, p=.419). Additionally, moderation by gender and vocation were not supported in either model. Taken together, the present results support that examining psychological and health outcomes among Black young adults should include an evaluation of racial discrimination distress. Further, future studies should continue to evaluate sociodemographic factors in larger more representative community-based studies to better understand potential variation in risk among Black young adults
