Proven for: Chronic neuropathic pain
Of all the different health issues that are treated with medical marijuana, this one has the most scientific support. It's good news, because neuropathic pain affects people with a variety of diseases – like diabetes and multiple sclerosis – and physical trauma. Studies from the Center for Medicinal Cannabis Research, where Dr. Atkinson works, have found that pot can reduce a patient's reported pain intensity by about 34 to 40 percent (versus 17 to 20 percent with a placebo). What's more, the marijuana they use contains only about 1 percent to 8 percent of the psychoactive compound THC, whereas street versions of the drug often contain in the vicinity of 13 percent.
