Summary
Emerging adults are a particularly vulnerable group for experiencing the immediate and potentially lifelong negative impacts of habitual cannabis use, and trends suggest that cannabis use disorder (CUD) will soon escalate in this population. The proposed research will combine clinical pharmacology, non-invasive brain stimulation, and neuroimaging techniques to establish the brain mechanisms of cannabinoid-impaired decision-making processes in emerging adults with CUD. Results from this project will inform CUD prevention/treatment efforts in this high-risk group and address a growing public health concern.
