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. The Tenth Amendment (Amendment X) to the United States Constitution, which is part of the Bill of Rights, was ratified on December 15, 1791.[1] The Tenth Amendment states the Constitution's principle of federalism by providing that powers not granted to the federal government nor prohibited to the states by the Constitution are reserved, respectively, to the states or the people. So a Constitution written on hemp cannot be against or prohibit hemp, therefore according to our 10th amendment the STATES should have the RIGHT to have their own Marijuana Laws.
