Mixed Reviews for Medical Marijuana

(Fall 2015) Is medical marijuana helping the conditions it is used to treat? Researchers reviewed data from 79 clinical trials that were conducted to study the effectiveness of using marijuana to treat symptoms related to certain conditions. Of the 10 conditions studied, two were found to have “moderate-quality evidence” to support claims that marijuana use was beneficial (chronic pain and muscle stiffness in MS) and four had “low-quality evidence” (nausea and vomiting due to chemotherapy, sleep disorders, HIV-related weight loss, symptoms related to Tourette’s syndrome). No evidence was found to support the claims associated with the other four conditions.
