The "drug war" is an invention of the federal government. All they want from you is to pay your taxes, do what you're told, and don't ask questions. Once you give it to them, you don't have anything to say about it. It's not your turf anymore, it's theirs.
Cocaine Slurpees will be an invention of Seven-Eleven coming near you. That will happen once drugs are marketed everywhere for the lowest possible price.
As for your bureaucrats, they may be be obtuse and power-hungry, but we do need police to keep the streets safe. Streets will not be safe with your libertarian addicts wandering around and vicious gangs lurking in the shadows.
