Exploring the effects of cannabis legalization

In this study, researchers are exploring the effects of cannabis legalization in two clinical samples of patients from Homewood Health Centre and St. Joseph’s Healthcare Hamilton entering treatment for substance use disorder and concurrent disorders. Specifically, researchers aim to measure changes in cannabis use, changes in cannabis use disorder, and changes in the consumption of other substances, such as tobacco, alcohol, stimulants, and opioids. Researchers are also exploring how cannabis use may be related to other substance use and mental health symptoms.
