Cancer and Chemotherapy Side Effects
Approximately 12% of the patients in the RI Medical Marijuana Program were recommended medical marijuana by their medical practitioners for the treatment of cancer or chemotherapy.
One of the most common reasons that patients use medical marijuana is to treat negative side effects of chemotherapy, such as nausea and vomiting. As medical marjuana stimulates appetite, in addition to relieving symptoms of upset stomach, it reduces the risk for cachexia, more commonly known as wasting syndrome.

From the Institute of Medicine
"In patients already experiencing sever nausea or vomiting, pills are generally ineffective because of the difficulty in swallowing or keeping a pill down, and slow onset of the drug effect. Thus an inhalation (but preferably not smoking) cannabinoid drug delivery system would be advantageous for treating chemotherapy-induced nausea."

"Cannabinoids are undoubtedly effective as anti-emetic agents in vomiting induced by anti-cancer drugs. Some users of both [cannabis and Marinol] find cannabis itself more effective."
