New research on the use of medical marijuana among people with rheumatic conditions such as arthritis finds that more than 6 in 10 patients who used medical cannabis reported substituting it for other medications, including NSAIDs, opioids, sleep aids and muscle relaxants. Most patients further said that the use of marijuana allowed them to reduce or stop using those medications entirely.
“The primary reasons for substitution were fewer adverse effects, better symptom management, and concerns about withdrawal symptoms,” says the study, published this month by the American College of Rheumatology. “Substitution was associated with THC use and significantly higher symptom improvements (including pain, sleep, anxiety, and joint stiffness) than nonsubstitution.”
The findings, say authors at the University of Michigan Medical School, McGill University and the University of Buffalo, “suggest that an appreciable number of people with rheumatic diseases substitute medications with [medical cannabis] for symptom management.”
Data for the study came from an online, anonymous survey of adult residents of the United States and Canada, which was advertised on social media and through email contact lists of the Arthritis Foundation and Arthritis Society Canada. Of 1,727 completed surveys, 763 respondents said they currently used cannabis, while 655 said they’d never used marijuana and 268 said they’d used but since discontinued. Researchers analyzed responses of only those who said they were current cannabis users.
“Among 763 participants, 62.5% reported substituting MC products for medications, including nonsteroidal anti-inflammatory drugs (54.7%), opioids (48.6%), sleep aids (29.6%), and muscle relaxants (25.2%),” the report says.
