The US Food and Drug Administration (FDA) stated in a Q&A section titled "FDA Regulation of Cannabis and Cannabis-Derived Products: Questions and Answers," available at and last updated Apr. 3, 2019:

“FDA is aware that unapproved cannabis or cannabis-derived products are being used for the treatment of a number of medical conditions including, for example, AIDS wasting, epilepsy, neuropathic pain, spasticity associated with multiple sclerosis, and cancer and chemotherapy-induced nausea.

To date, FDA has not approved a marketing application for cannabis for the treatment of any disease or condition and thus has not determined that cannabis is safe and effective for any particular disease or condition.”
