PATIENT-REPORTED OUTCOMES IN THOSE CONSUMING MEDICAL CANNABIS: A PROSPECTIVE LONGITUDINAL OBSERVATIONAL STUDY IN CHRONIC PAIN PATIENTS
October 09, 2020
In this observational study conducted by Dr. Hance Clarke et al, around 1000 patients with Chronic diseases from multiple Cannabis Clinics in Toronto, Canada were enrolled between Sept 2015 and Jul 2018. Patients completed questionnaires at different times of their medical visits, by which their demographics, patterns of cannabis use and the long-term effectiveness of cannabis on their pain, anxiety, depression, quality of life, general health symptoms, self-reported opioid consumption, and adverse events were assessed. 217 (28%) completed the six-month questionnaire and reported continuing the consumption of cannabis. Pain scores were significantly reduced, and quality of life was improved.
Although 28% represents only about a third of the patients included in the study, these results contribute to the current evidence on cannabinoid-based medicine and highlight the need to continue conducting well-designed controlled studies not only on the therapeutic effect of cannabis but also on the type and quality of accessible cannabinoid products in real life.
