CMCR studies

Current studies examine the effects of cannabis and cannabinoids on a range of psychiatric, developmental and pain conditions, as well as the impact of use on public safety (e.g., driving). A list of current and past studies can be found here.

PROJECT TITLE: Cannabis Use and the Endocannabinoid System in Bipolar Disorder

PROJECT TYPE: Clinical Study

STATUS: Active


This study will look at the impact of chronic cannabis use as well as the effects of acute administration of the principal constituents of cannabis on cognition and brain levels of endogenous cannabinoids and the neurotransmitter dopamine.

Cannabis use is highly prevalent in people with Bipolar Disorder (BD) and likely results in significant cognitive and behavioral disturbance in a population already vulnerable to cognitive deficits. Parallel studies in rodent models of BD will enhance the understanding of the neurobiology of cannabis use from acute, chronic, and withdrawal perspectives, and may ultimately lead to novel treatment targets.
