Taking a slightly different turn from the medical view of things:
I just recently discovered some herbs (goldenseal, nettle) that seem to be really helping me in treating my allergy symptoms. I am so thankful to discover them, because I hate taking prescription drugs that just give me a whole new spectrum of issues. Similarly, I think it would be silly not to allow marijuana to be used for all of its medicinal purposes. People are getting seriously hooked on prescription pain meds... Anything to get away from the horrible side effects of of the pharmaceuticals is a good thing.
