It is already greatly proven that medical marijuana can actually help patients with debilitating diseases that other medicine can not help. It can help reduce stress, anxiety, depression, lack of appetite, it can even help those who feel that their treatment is to harsh wean down from their normal medication levels.
Marijuana should be used for medical purposes. Studies have shown it does actually help people. My Uncle suffers from chronic back pain from working as a mover. The drug helps with the pain. My roommate also has a card for marijuana and uses it. She suffers from headache constantly. They seem much happy once they recieved their prescriptions.
