“Use of marijuana to ease back pain was common among patients at a university spine clinic in Colorado where pot has been legal for medical purposes since 2000, but most of the users did not have a prescription, according to research presented here.

Among 184 patients at a Colorado spine center, 19% said they used marijuana for pain relief, but less than half, 46%, actually had a prescription for the drug, according to study co-author Michael Finn, MD, an assistant professor of neurosurgery at the University of Colorado in Denver.

The most common way to use the drug was smoking it, 90%, followed by oral ingestion, 45%, and vaporization, 29%.

According to the users, marijuana worked. A total of 89% said it greatly or moderately relived their pain, and 81% said it worked as well as or better than narcotic painkillers.”
