A study conducted last year suggests that smoking cannabis is an effective pain reliever. The majority of cannabis users most likely already know this, as did cannabis users over the past thousands of years. However, it will take more scientific research to convince decision makers of its effectiveness.
A summary of the study is available here.
Here is an excerpt:
The study used capsaicin, an alkaloid derived from hot chili peppers that is an irritant to the skin, to mimic the type of neuropathic pain experienced by patients with HIV/AIDS, diabetes or shingles – brief, intense pain following by a longer-lasting secondary pain. The subjects were healthy volunteers who inhaled either medical cannabis or a placebo after pain was induced. The marijuana cigarettes were formulated under NIH supervision to contain either zero, two, four or eight percent delta-9-tetrahydrocannabinol (THC.)
“Subjects reported a decrease in pain at the medium dose, and there was also a significant correlation between plasma levels of THC, the active ingredient in cannabis, and decreased pain,” said Igor Grant, M.D., F.R.C.P.(C), professor and Executive Vice-Chair of the Department of Psychiatry, the director of the CMCR. “Interestingly, the analgesic effect wasn’t immediate; it took about 45 minutes for the cannabis to have an impact on the pain,” he said.
