Marijuana's therapeutic uses are well-documented in modern scientific literature. The studies indicate that marijuana provides symptomatic relief for a number of medical conditions, including nausea and vomiting, stimulating appetite, promoting weight gain, and diminishing intraocular pressure from glaucoma. There is also evidence that smoked marijuana and/or THC reduces muscle spasticity from spinal cord injuries and multiple sclerosis, and diminishes tremors in multiple sclerosis patients. Patients and physicians have also reported that smoked marijuana provides relief from migraine headaches, depression, seizures, insomnia and chronic pain, among other conditions.
