Study Summary
This project examines the effects of cannabis on cognition and other domains of function and whether those effects are dependent upon the ratio of THC to CBD in the product. Current cannabis users are asked to stop using their typical product and to use cannabis containing different ratios of the cannabinoids THC and CBD. Participants complete baseline assessments including cognitive tasks, clinical measures, substance use history, and blood draw. Participants then acquire and use their study strain on their own, and after a period of use the mobile pharmacology laboratory goes to a location of their choosing. They complete cognitive, motor and blood-based assessments, then leave the mobile lab to use their study product one last time, returning to the mobile lab to complete cognitive, motor, and blood-based assessments immediately after use and one hour after use. A small subset of participants complete all of these procedures but use edible as opposed to flower-based products.
Primary Outcome
To test the hypothesis that a high delta-9-tetrahydrocannabinol (THC) strain of marijuana will be associated with greater blood levels of THC and greater harmful effects, we will measure the concentrations of the cannabinoid THC in blood (ng/ml).
