I know you're joking, but I'm pretty sure I'm older than you are.
As far as being legalized for medical use in US, that's really just a back door way of legalizing it in a few states. It's still illegal under the Federal law, which takes precedence. It may be available in pill form legally by prescription, I've heard that but I'm not sure. Certainly FDA wouldn't approve a medication that's delivered by smoking and has no dosage, since it obviously damages the lungs.
