Cannabinoids...NOT smoked marijuana. And quote the rest.
"Conclusions and Relevance There was moderate-quality evidence to support the use of cannabinoids for the treatment of chronic pain and spasticity. There was low-quality evidence suggesting that cannabinoids were associated with improvements in nausea and vomiting due to chemotherapy, weight gain in HIV infection, sleep disorders, and Tourette syndrome. Cannabinoids were associated with an increased risk of short-term AEs."
This isn't smoked marijuana. It's clear that drugs made from marijuana are pretty crappy when taken as a whole. There are better drugs for each of these. Yet when people talk about "medical" marijuana they're talking about a bunch of stoners who go to "clinics" to get their pot supply. That's ALL it is.
