The cannabis plant has a history of medicinal use dating back thousands of years across many cultures. Its usage in modern times is controversial, and in recent years the American Medical Association, the MMA, the American Society of Addiction Medicine, and other medical organizations have issued statements opposing its usage for medicinal purposes.
Medical cannabis has several potential beneficial effects. Cannabinoids can serve as appetite stimulants, antiemetics, antispasmodics, and have some analgesic effects, may be helpful treating chronic non-cancerous pain, or vomiting and nausea caused by chemotherapy.
