RecruitingDrug trialStudy of Cannabidiol and Neuroimaging on StressDysregulation in stress responsivity is a growing psychiatry-transdiagnostic fundamental phenomenon, with limited therapeutic strategies. With the legalization of medical and recreational cannabis, many people consume cannabidiol (CBD; a nonintoxicating cannabinoid) to alleviate stress response, without the benefit of scientific guidance. To address this gap, the investigators propose a rigorous translational neuroscience study in a clinical high-risk population to define the roles of CBD in stress response with mechanisms of mesocorticolimbic-network function and hierarchy, neurometabolic, endocrine, and behavior, building upon convergent evidence from animal models and human evidence from our laboratories.
