Nice strawman. That isn't what I said and wether something has a "responsible use" is irrelevant.
The use of something is not, and cannot, be a crime. It is the misuse of something that is a crime. This applies to guns, drugs, cars, knives, baseball bats, and liquor.
If somebody intoxicates himself with liquor and then drives his car over somebody then hold the individual accountable for his actions. But, don't institute prohibition of alcohol or cars.
Because some have chosen to abuse their freedom is no justfication to restrict the freedom of all.
SO if I USE a nuke on my property, it can't be a crime? That's idiotic. The point here is other's rights. When you put crack or meth, ect in your body, you no longer can control yourself, not even as much as a person that had a few beers can. You are incapable of acting responsible and you are a threat to me, as your neighbor. You are violating my rights, and the gov has the moral authority to step in.
