A new metastudy of numerous randomized controlled trials has found that cannabis is a safe, effective treatment for chronic pain. The study was published in the Journal of Neuroimmune Pharmacology, and was published online Monday by the National Institute of Health.
The study, conducted by researchers at Pharmacology Dalhousie University‘s Departments of Anesthesiology in Canada, was an “updated systematic review of randomized controlled trials examining cannabinoids in the treatment of chronic non-cancer pain was conducted according to PRISMA guidelines for systematic reviews reporting on health care outcomes”, according to the study’s abstract.
“Eleven trials published since our last review met inclusion criteria”, says Dr. Mary Lynch, the study’s lead researcher. “The quality of the trials was excellent. Seven of the trials demonstrated a significant analgesic effect. Several trials also demonstrated improvement in secondary outcomes (e.g., sleep, muscle stiffness and spasticity). Adverse effects most frequently reported such as fatigue and dizziness were mild to moderate in severity and generally well tolerated.”
Lynch concludes that; “This review adds further support that currently available cannabinoids are safe, modestly effective analgesics that provide a reasonable therapeutic option in the management of chronic non-cancer pain.”
