Not a single case of the Courts holding that it was "unConstitutional" for the "FedGov to ban substances or objects."

Sorry, you got an F.

Try the extra credit question.

Sure there was. That was why the "marijuana tax stamp act of 1937" was passed, so that they could do an end-around the court. The court had previously rule AGAINST such bannings as a violation of the 4th and 5th amendments so the Congress critters devised a scheme that let them place a special tax on the stuff they wanted to control (NFA, 1934) and later expanded that to pot. Of course, NO TAX STAMPS were ever issued for pot, nor was there any intention of doing so. That is why the 1937 act was declared unconstitutional when it was finally challenged and why the Congress finally just gave up any PRETENCE at constitutionality in '68 and subsequently.
