I see more and more "drug free zone" signs popping, and I have to wonder. First of all, all ZONES should be drug free as illicit drugs are illegal even outside dedicated drug free zones. I understand that penalties are higher in these dedicated zones (mostly schools) but that does not require these signs to be put up. You just make laws to that effect. I highly doubt that drug dealers pay much attention to any such signs. Maybe we should also designate some "murder-free zones" and some "robbery-free zones". Me personally, I would like to live in a "zone-free zone".
