It found INSUFFICIENT EVIDENCE to support that cannabis/cannabinoids are effective treatment for:
• Cancers, including glioma (cannabinoids).
• Cancer-associated anorexia cachexia syndrome and anorexia nervosa (cannabinoids).
• Symptoms of irritable bowel syndrome (dronabinol).
• Epilepsy (cannabinoids).
• Spasticity in patients with paralysis due to spinal cord injury (cannabinoids).
• Symptoms associated with amyotrophic lateral sclerosis (cannabinoids).
• Chorea and certain neuropsychiatric symptoms associated with Huntington’s disease (oral cannabinoids).
• Motor system symptoms associated with Parkinson’s disease or the levodopa-induced dyskinesia (cannabinoids).
• Dystonia (nabilone and dronabinol).
• Achieving abstinence in the use of addictive substances (cannabinoids).
• Mental health outcomes in individuals with schizophrenia or schizophreniform psychosis (cannabidiol).

The National Academy of Science called for more and better research.
