just for the record, you still can't legally be prescribed medical marijuana in the US. a doctor can recommend it, but then you have to apply for an ID card showing you are allowed to grow and possess it.
even though i don't use either, i definitely think both medicinal and recreational marijuana should be legalized. medical marijuana is one of the safest forms of medication and it can treat a wide variety of conditions. using it recreationally has very few bad side effects (unless you get addicted to it, but that's a moot point) compared to other drugs and the state can tax the hell out of it, so it's a win-win situation.
