a median 20% reduction in pain symptoms, the researchers found. Median means half had greater pain reduction, half had less.
Study participants also reported other benefits.
Anxiety levels dropped by a median 22% and depression severity by 12%. At the same time, quality of life scores rose by a median 14%. In all, about 60% of participants reported improvement in symptoms tied to medical marijuana, the investigators found.

“Medical cannabis has been suggested as a possible remedy for appetite loss; however, most patients in this study still lost weight,” Meiri says. “As a substantial portion were diagnosed with progressive cancer, a weight decline is expected with disease progression.”

“Let’s say you have chronic pain and you’re watching an interesting movie on TV, for two hours you don’t think about it, but when the movie is over you start feeling pain again,” he says. “Cannabis is the same effect. Pain may be still there and the reduction in pain is not dramatic, but patients cope better with the pain. Quality of life unquestionably improves with cannabis.”
