"You keep using that word. I do not think it means what you think it means."
Well, you know the old adage about leading a horse to water, right?
You're arguing against the idea of taking Constitutional limits on principle, that we should make exceptions for this or that, that each law should be judged on a case-by-case basis (and that in this case ignoring the constitution is perfectly justified because, "drugs are bad, mkay?"). Well, that's exactly the view of every 'living document' yahoo that wants us to ignore the constraints the Constitution imposes on the state for their pet cause. You surely think your fear of drugs is a 'special' case, but constitutions don't work that way. They codify general principles and set limits on the kinds of laws government can impose on us. When the court decides that the federal government has the power to tell us what drugs we can take it establishes a precedent and, from then on, they have the power to make similar decisions for us. It's not a 'slippery slope', it's a door that's either closed or open.
I see you dont have a clue as to what I actually believe, despite numerous pages of posts here. I don't know whom you are responding to, but it isnt me in any recognizable way.
There is no guarantee in the Constitution for a right to do drugs. There is none.
There are powers granted to the government that are constantly interpreted, because that's how law works. Currently no court has ever held the Fed gov't does not have the power to regulate drugs. Much less state governments, which is where a lot of minor drug cases end up.
So you are simply incorrect on your understanding of the Constitution.
As to drugs themselves, you take the narco-libertarian approach that people are not hurting anyone when they take them. That is demonstrably untrue. Look at any inner city and many rural areas for that matter and amid the poverty and misery you will always find drugs. Always. If someone lives on a ranch in Montana and his nearest neighbor is 5 miles you might have a point. But most people don't.
Once I point this out you engage in slippery slope fallacies to say, Well if you want to ban drugs then you also need to ban XY and Z. No, I don't. That is why it is called a fallacy. Every item is an independent case with difference circumstances. You cannot argue the merit of drugs alone without resorting to false comparisons with other things.
So we have established that drugs are harmful. And we have established that the government has the power to restrict the trade. The case is closed.
