A comprehensive review of medical literature published by the National Academies of Sciences, Engineering, and Medicine found conclusive and substantial evidence that cannabis is effective in the treatment of spasticity associated with multiple sclerosis. The review also found strong support for cannabis use in the treatment of pain and adults and chemotherapy-induced nausea. However, evidence supporting use in irritable bowel syndrome and several other conditions was found to be limited, insufficient, or absent.

A systemic review of 28 databases also found moderate-quality evidence to support the use of cannabinoids for the treatment of chronic pain and spasticity due to multiple sclerosis or paraplegia. However, use in other conditions was either supported by low-quality evidence or unsupported. A recent Clinician's Guide to Cannabidiol and Hemp Oil concluded that these products are promising for chronic pain relief, but further education and investigation are necessary.

In a position statement on the use of medical marijuana, the Tourette Association of America found that no evidence supports the use of cannabis alone in treating Tourette syndrome. Cannabis use has also been linked to increased risk of developing schizophrenia and other psychosis.
