Fear of meth worse than meth itself

Having been up since before dawn, I'm fading fast tonight so I'm just going to say this is a really stupid idea and I'm sorry to see it gaining steam in the states. A meth offender registry is going to cause more trouble than it solves and I can't imagine a better way for a curious teenager to seek out the drug than to advertise the people who know how to get it and/or make it. What are these people thinking?
