They did, in the negative. They listed ONLY the things the federal government was to regulate. Don't like it, don't trash the Constitution, change it.
States have laws against all those things, including drugs, and the Fed not only has no authority, it is needless, and grows federal government.
I want to see the Fed Government crushed back into the constitutional box it came it.
