Let me expand and clarify it. Is the federal government authorized by the Constitution to make illegal the possession of any substance that it deems it to be harmful, hazardous, immoral, addictive, threatening, damaging, injurious, destructive, unsafe, or dangerous to an individual or to society?

I am not talking about state governments—that is a separate issue. I am talking about the U.S. national government that was set up by the Constitution in 1789. The Constitution that was amended in 1791, 1795, 1804, 1865, 1868, 1870, 1913, 1919, 1920, 1933, 1951, 1961, 1964, 1967, 1971, & 1992. The Constitution that is the supreme law of the land. The Constitution that all conservatives claim to revere. The Constitution that all conservatives say they expect the federal government to follow. The Constitution that conservatives drag out and dust off every time there is an election. The Constitution that the Republican Party says it is the party of. The Constitution that all members of Congress swear to support and defend. The Constitution that the president swears to preserve, protect, and defend. The Constitution by which the Supreme Court is expected to judge all laws.
