We are Conducting
The Largest Observational Study on Cannabis in Canada
Canadian Cannabis Clinics recently partnered with CanvasRx Inc. and Drs. Hance Clarke and John Hanlon to launch what will be the largest observational study of medical cannabis of its kind in Canada. We hope to enrol 1,000 patients and observe them over the course of 12 months.
The study is designed to identify any beneficial or adverse effects of inhaled (smoked or vaporized) cannabis prescribed by our 24 clinic locations in Ontario.
The study is a multicentre, longitudinal, non-interventional, observational study designed to provide an understanding of the beneficial and adverse effects of cannabis. All patients in the study will be 25 years or older, who have been prescribed cannabis for a chronic condition. Participants will be asked to self-administer validated pain, psychological and sleep questionnaires throughout the study. The study team includes Drs. Hance Clarke (MD PhD FRCPC), John Hanlon (MD, MSc, FRCPC), Howard Meng (MD) and Laura Zielinski (MSc).
