Ok, it's finally happened. Washington and Colorado have both legalized the possession, production, and sale of marijuana for recreational use. The drug remains illegal on a Federal level. Will the Fed actually try and enforce that law without the cooperation of state authorities? With no border controls at all between states, how can the Fed possibly hope to contain legal marijuana production in two states from spilling over into the rest of the country, particularly the west? Is this the beginning of the end of the Federal ban?
