While clinical trials are lacking, surveys of patients have helped researchers identify the most common reasons for using medical marijuana.

Recently, a team at the VA Palo Alto Health Care System surveyed 217 patients at a dispensary in California to find out what cannabis might be helpful for.

These were the results (patients could choose more than one):

The survey also revealed a much longer list of uses, but reported less commonly. The entire list of benefits reported by patients were:

"HIV/AIDS, nightmares, arthritis, glaucoma, cancer, attention deficit disorder/attention deficit hyperactivity disorder, neuropathy, asthma, seizures, bipolar disorder, Crohn's disease, epilepsy, hepatitis C, emotion regulation, restless leg syndrome, broken back/spinal cord injury, diabetes, hypertension, irritable bowel syndrome, multiple sclerosis, premenstrual dysphoric disorder, sciatica, recovery from surgery, alcohol over-consumption, allergies, borderline personality disorder, boredom, breathing, symptoms related to being burned, carpal tunnel, tendinitis, chronic fatigue syndrome, cyclical vomiting syndrome, dermatomyositis, digestions/polyps, Dupuytren's contracture, fibromyalgia, former lateral epicondylitis, gastroparesis, Grave's disease, hydrocephalus, intestinal bleeding, lack of motivation, leg cramps, loss of arm, neuralgia, post-viral refractory fatigue, tapering off opiates, tenosynovitis, anger and mood swings."

Contrary to popular belief, it appears it's not just pain that marijuana can be good for.
