SURVEY: Pain patients overwhelmingly prefer medical marijuana over opioids.

Though the survey, involving 2,897 medical cannabis patients, didn’t track actual drug use or efficacy, the findings fits with previous data. Decades of research suggest marijuana is effective for pain treatment. And recent studies have found that in states with medical marijuana availability, there are fewer opioid overdose deaths and doctors fill fewer opioid prescriptions.

The authors of the new survey, led by Amanda Reiman of the University of California, Berkeley, say the data furthers the need to examine marijuana as a “viable substitute for pain treatment,” particularly in light of the devastating opioid epidemic now gripping the country.

It’s only one study, but THC would seem to be less harmful longterm than opioids, particularly if ingested orally rather than smoked.
