The 10th Amendment of the U.S. Constitution states: “The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.” There has been some push-and-pull on this, with the federal government not wanting to give power to the states and frequently trying to hide behind the “Interstate Commerce Clause,” particularly when it comes to Marijuana issues.

I would hope the various states would have the courage to stand up to the federal government’s malfeasance when it comes to Marijuana.
