Anxiety severity and prescription medication utilization in first-time medical marijuana users

Anxiety and post-traumatic stress disorder (PTSD) are qualifying psychiatric conditions for medical marijuana (MM) treatment in Pennsylvania. This study examined baseline prevalence and changes in prescription anxiety medication use three months following MM treatment initiation among individuals with these qualifying conditions. The study sample was comprised of 108 adults with anxiety or PTSD as a referring condition; they were enrolled in a longitudinal study evaluating biopsychosocial outcomes in new MM patients. Consenting participants completed an assessment battery at baseline and Month 3 (n = 94, 87 % follow-up rate) that included a measure of anxiety severity and questions about current anxiety medication prescription and desired (baseline) and actual (Month 3) reductions in medication use.
