Marijuana And Chemotherapy

I am writing a research paper on medical marijuana to chemotherapy for my English class, and my position is against it. One of my points is that it is difficult to regulate marijuana and probably very expensive and are not insured, so that drugs like Marinol are. so I guess I want to know if I was a cancer patient in a state of medical marijuana, how many grams of quality of some of it cost me?

Each ounce is about $ 300
