I don't believe it! Only in the US! Let me ask you this: how can you expect that kind of legislation to work?
Sorry, no. pubescant kids will be pubescant kids, prohibiting behaviour like that will not stop it from happening.
Compare with the war on drugs, they're illegal but their usage is increasing. The US is blindly telling everyone "thou shalt not", but only people with really closed minds actually buy their arguments; they haven't worked on solving the root causes of the problem; mainly lack of understanding by the general public, and the greed of black market dealers. Another thoroughly ineffective piece of legislation from the US.
