pondering medical marijuana

I heard on the news today that a veteran's association is trying to get the government to approve the use of medical marijuana to treat veterans. I have never smoked marijuana or even eaten a marijuana brownie, not, you understand because of a particularly high moral or ethical stance (although I will admit that I've never liked the idea of loosing control of my mental facilities, even temporarily) but primarily, i guess, because I was never offered any in college or later. I must have led a very sheltered life. But getting back to the idea of using marijuana as a medical treatment, I actually think that's a very good idea. I remember learning, years after my mother died of cancer, that marijuana can be very effective in treating nausea. Back in the 60's her chemo therapy involved a week of treatment followed by two weeks of feeling nauseous followed by one week of feeling pretty good. Then the whole process started over. I've know of other people too who became agonizingly thin during chemo therapy because they always felt too sick to eat. If there is a treatment out there that can overcome the nausea and kill some of the pain then why not use it? If I should ever end up with cancer I hope someone will bake me some brownies.
