Study Summary

This trial will explore the link between cannabis use disorder, brain activity, and cognitive function to see how they affect each other.

Who is the study for?
This trial is for adults with Cannabis Use Disorder (CUD) who have used cannabis more than 20 times but don't have other substance use disorders or major psychiatric conditions. They must be physically healthy, not pregnant or breastfeeding, and have an IQ over 80. Healthy controls (HC) with no recent cannabis use can also participate.Check my eligibility
What is being tested?
The study investigates how stopping cannabis affects brain chemistry, brain waves, and thinking in people with CUD using PET scans to measure a specific receptor and EEG to monitor brain activity. It compares these findings between regular cannabis users and non-users.See study design
What are the potential side effects?
Potential side effects may include discomfort from abstaining from cannabis for those with CUD. The PET scan involves exposure to a small amount of radiation. MRI imaging might cause discomfort due to the enclosed space or noise during the procedure.
