We investigated cannabis involvement and the contribution of trauma exposure to cannabis initiation and transition to cannabis problems in EA and AA women. The likelihood of developing CUD symptoms was higher in AA than EA women who had tried cannabis, but no differences between rates of cannabis initiation or ages of onset for cannabis initiation, time of first CUD symptom, transition time from cannabis initiation to first cannabis problem were discovered. AA women did report elevated rates of PTSD, MDD, and trauma exposure (with the exception of experiencing a disaster) as compared to their EA counterparts.
