What difference does that make? I constantly hear that "there is no constitutional authority to ban drugs." So if there is no authority to do it, then it doesn't matter if it's international or interstate. There's no authority, remember?
Not the same thing at all.
Yes, a lack of authority to ban drugs within our borders is completely different from a lack of authority to ban drugs from outside our borders. Totally different. Absolutely.
If you don't see a difference between using the Constitution internationally, and nationally, that is your blind spot.
Personally, after looking at your home page, I expect you are no friend of freedom or the Constitution. You just seem to like to argue.

Anybody who actually reads the Constitution knows that the federal government has authority over import and export laws, but not over most ordinary domestic matters.
