Researchers


Do you regularly use cannabis?

Centre for Addiction and Mental Health (CAMH),


We are interested in understanding the cause of cannabis withdrawal syndrome and how it affects the brain. We are looking for participants who are 17-65 years of age who regularly use cannabis are willing to abstain from using cannabis for approximately 1 week. The goal of this study is to take pictures of a brain enzyme called fatty acid amide hydrolase (FAAH), which may be implicated in cannabis withdrawal syndrome. Knowing more about this enzyme can help us contribute to the development of new treatments and learn more about how it affects those with cannabis withdrawal syndrome.
