Cannabinoids for Osteoarthritis Pain Effectiveness Trial

This study aims to investigate whether oral cannabis extracts can effectively manage pain caused by osteoarthritis (OA), a common joint condition affecting one in seven Canadians. Current OA treatments often have limited effectiveness and may cause side effects. As a result, many individuals with OA turn to medical cannabis for pain relief, despite limited scientific evidence supporting its efficacy. The goal of this study is to assess the feasibility of a larger trial evaluating the effects of two cannabis compounds-CBD and THC-compared to a placebo (a look-alike substance containing no active drug) on pain interference in patients with hip and/or knee osteoarthritis. Participants will: * Take either CBD, THC, or a placebo capsule daily for 8 weeks * Complete follow-ups remotely, with no in-person clinic visits required * Maintain a diary tracking their study drug usage and any additional pain medications
