Haha I teach one of those classes sometimes at the youth center. Well, ok, I have only taught it once so far and helped with it another time. But still.

I don't see the harm in it either. The pros outweigh any cons there may be. And the government would certainly benefit from it. Imagine how much money they could make if it was completely legal and they taxed it like they do cigarettes. They'd get so much money.
