Illegal drugs are illegal for a reason. Sure, maybe try marijuana once in a lifetime, but I don't really see the point in legalizing it. We already have enough stupid people in the world, we don't need stupid and high people in the world. No offence, but with the quite loose gun-law in America, think of the horrible accidents that could happen if illegal drugs were legallised everywhere. And if you are indeed desperate to do drugs, you can always go to Colorado.
But hey, that's just my stance on the matter. It's not something that I really pick on when someone does drugs, it's their own choice.
