The Association between Potentially Traumatic Events and Cocaine, Cannabis, and Alcohol Use Differs by Race.

: Although exposure to potentially traumatic events (PTEs) for Black and Latinx may be comparable or lower than their White counterparts, type of trauma experiences differ such as more interpersonal trauma and violence reported by Black people, who also experience higher rates of PTSD. In this retrospective study, we examined the association between use of particular substances and various PTEs and the race/ethnicity-group differences for this association. : One-hundred seventy-nine participants recruited from an outpatient substance use disorder program from February 2018 to October 2020 completed measures on lifetime trauma history and current/past cocaine, cannabis, and alcohol misuse.
