Consider:
Because the Federal Government had no power to regulate what people consume or do not consume, it took this to ban alcoholic beverages:
Amendment XVIII:
Section 1. After one year from the ratification of this article the manufacture, sale, or transportation of intoxicating liquors within, the importation thereof into, or the exportation thereof from the United States and all the territory subject to the jurisdiction thereof for beverage purposes is hereby prohibited.
Section 2. The Congress and the several States shall have concurrent power to enforce this article by appropriate legislation.
Section 3. This article shall be inoperative unless it shall have been ratified as an amendment to the Constitution by the legislatures of the several States, as provided in the Constitution, within seven years from the date of the submission hereof to the States by the Congress.
None of those powers were part of the Constitution, nor delegated to the Federal Government prior to the ratification of the Amendment. When the Amendment was repealed, those powers should have returned to the States, or to the people.
Which means the regulation of what you consume or do not consume remains a power reserved to the States or the People, not the Federal Government.
