The objective of the current study is to prospectively assess the effect of cannabis on pain and functional outcomes in a large group of patients with chronic pain.
This is a prospective, observational, open-label study carried out at the ambulatory pain clinic of Hadassah-Hebrew University Medical Center Pain Relief Unit. Study population: Patients suffering from chronic pain that has not been relieved with other analgesic medications, who are eligible for treatment with medical cannabis (cigarettes, oil or cookies) following approval of Israeli Ministry of health.The patients will receive a prescription to be dispensed at pre-approved cannabis distribution points by a certified provider.
