Okay, I take ginger for car sickness and I find that it works just as well for me as Dramamine, and I put aloe on burns, and I would absolutely consider taking marijuana for chemo nausea, but you really need to think hard about using a known carcinogen that "they" told you would heal your ails.
I just watched a movie recently: Fat, Sick and Nearly Dead, and I do believe that there might be something to say for using Gods own bounty for healing, but the difference is, it can't make the situation worse.
