The unconstitutional matter of the FED telling us what we can and cannot put in our bodies is unconstitutional because it overpowers the states. THAT is why it is unconstitutional. The STATES, are states, therefore are not overpowering the states. Thusly, prohibitional laws by the states are not unconstitutional.
The FEDERAL prohibition on alcohol required an AMENDMENT, yet the states did not.
Mmmmm, -- then in your view state governments have been given the constitutional power to tell "us what we can and cannot put in our bodies"?
-- Where do you see this prohibitionary power enumerated or implied?
And, -- does this view of yours mean that any prohibitive state law cannot be "overpowered"?
