cannabis

Cannabinoids have been shown to be possibly analgesic in animal models of neuropathic pain. There have been a few studies of marijuana/9-THC employing different models of experimentally induced pain in volunteer subjects or cannabis seeds, and these studies have also yielded conflicting results. Raft and colleagues (1977) found that, in oral surgery patients, premedication with intravenous 9-THC was less effective than diazepam or placebo in reducing two kinds of experimentally induced pain.
