Study Results from Institute for Mental Health in the Area of Marijuana/Cannabis Reported (The Effects of Extended Cannabis Abstinence in Comorbid Posttraumatic Stress Disorder and Cannabis Use Disorder).

This article focuses on a preliminary open-label study conducted in Toronto, Canada, examining the effects of 12 weeks of cannabis abstinence on posttraumatic stress disorder (PTSD) symptoms in individuals with comorbid PTSD and cannabis use disorder (CUD). The study found that participants who maintained abstinence showed significantly greater reductions in overall PTSD symptom severity, particularly in avoidance, negative mood and cognition, and hyperarousal, compared to those who did not abstain. The research suggests that continued cannabis use may hinder recovery in some PTSD symptom domains and highlights the importance of assessing cannabis use during PTSD treatment. The study calls for larger randomized trials to confirm these findings and explore the mechanisms linking abstinence to symptom changes. [Extracted from the article]
