Cannabidiol as a Treatment for AUD Comorbid With PTSD

600 mg daily

This project aims to determine whether cannabidiol (CBD) is effective in treating alcohol use disorder (AUD) comorbid posttraumatic stress disorder (PTSD). To address this aim, investigators will conduct a clinical trial in which CBD will be administered to 48 individuals with AUD comorbid with PTSD, and assess alcohol intake and PTSD symptoms. The aim is to test the hypothesis that CBD will reduce alcohol drinking in individuals with AUD comorbid with PTSD. To test this hypothesis, 48 otherwise healthy adult participants with moderate or severe AUD and PTSD will be randomized to treatment with either CBD (600 mg daily) or placebo, for a period of 6 weeks, such that both participants and study staff are blind to treatment condition.
