By legalizing it, all you're saying is that marijuana is NOT a drug in the way that coke, meth, heroin, etc is. You're basically putting it in the same category as cigarettes and alcohol (which realistically, it SHOULD be considered as).

Legalizing marijuana isn't going to tell the kiddies that cocaine is ok, too. At least, not anymore than the cigarettes and alcohol already do. All it's going to do is tell kiddies that their parents aren't criminals because they get high every once in a while. I don't see that as a bad thing.
