The Medical benifits The medical benifits that medical marijana brings is huge to without taking other medicine that don't work. I know 2 people that have brain tumours and the person taking marijuana is getting married with a bright future the other I'm sorry but didn't make it :( and so sad. Quality of life will matter in the end and results. Marijanan is a cure and treatment well big pharma will have to see that if not they are digging there heads n the sand.
