Vortioxetine improves illness severity for cannabis users with anxiety and depressive symptoms in a 6-month randomized controlled study.

Introduction: Cannabis use and misuse have mental health implications, particularly affecting mood and anxiety symptoms. Vortioxetine, a potent serotonin partial agonist/antagonist reuptake inhibitor antidepressant, has well-established effects in treating depressive and anxiety disorders and may serve as a potential treatment for individuals with cannabis use disorder and comorbid mood symptoms. In the current study, we aimed to investigate the efficacy of vortioxetine for cannabis users with anxiety and depressive symptoms alongside their cannabis dependence.
