A new review of more than 120 studies concluded that there is little evidence supporting the use of medical cannabis for a variety of conditions, including insomnia.

The U.S. Food and Drug Administration has approved cannabinoids, a chemical compound extracted from cannabis, for chemotherapy-induced nausea and vomiting and seizures, among other conditions. Many patients use cannabinoids or other medical cannabis for other conditions, such as anorexia, insomnia, and chronic pain, either through off-label prescriptions or through state availability.
