On the constitutional side, I'm also confused about the US rulings on this. IIRC, 1 state has voted to legalise medicinal use of pot and another is about to vote, but the federal government is insisting that federal laws override state laws, so you can still be busted for it. I bet that's going to be an interesting one for the constitutional lawyers to sort out - this'll keep the legal beagles in work for years!
