I dont think the legalization of weed will increase the usage among kids, they have it more available than most adults. As said before it is the parents teaching kids to make educated decisions that keeps them off the weed, booze, pole, sex, heroin, etc.

Most parents have the ability to guide their children... Unless they are ok with the government telling parents how to raise kids, parents should quit it with using their kids to influence government.

Keeping weed illegal allows government programs to make enough "drug busts" to retain the budgets they receive year after year. If they relied on other drugs they would loose money. Saying "We made 4749 drug busts this year" sounds much better than saying "We busted 4000 kids with weed and 749 meth heads".

I say legalize it at this point, I would say decriminalize it but I think the US could use the cash.
