We leave no stone unturned. In 1999, the Institute of Medicine, a branch of the National Academy of Sciences, made the strongest case to date for cannabis as a potentially effective treatment for nausea, AIDS-related appetite loss, glaucoma, multiple sclerosis and other ailments. Recent findings suggest that THC holds more potential as a painkiller than anyone ever guessed. Discoveries that the body produces its own cannabinoids that bind with receptors located in the brain and elsewhere lead scientists to believe THC could affect nerve impulses between cells in precise ways. It's a very exciting science question.
Some scientists remain skeptical.
There is still very little controlled clinical research on cannabis that demonstrates medical benefit.
