No. Congress is using the power given to them by the Necessary and Proper Clause to write laws which would prohibit citizens from interfering with their constitutional regulation of the interstate commerce of drugs.
These drugs never crossed a state line, nor did the wheat in the case cited. There was no buying or selling of any kind involved. Nothing changed hands. In this use of the concept of "commerce", our federal government could make masterbation illegal. The need to regulate sperm banks would make it the federal government's business.
