Nothing has been of greater benefit to the global drug trade than the US government’s war on it. From Jacob G. Hornberger at fff.org:
Pardon me for being blunt, but it would be difficult to find anything more idiotic than the war on drugs, an ongoing federal program that has been enacted and enforced by both Republicans and Democrats for decades. The program is sheer idiocy in that its supporters continue to keep it going despite the manifest failure, violence, ruination of lives, expense, racism, and destruction of liberty and privacy that this federal program has produced and continues to produce.
But hope springs eternal in the minds of the drug war’s supporters and enforcers. Each new drug bust over the decades, oftentimes accompanied with a large amount of hoopla from the mainstream press, provides these people with confirmation that victory is just around the corner. Just a few more drug busts and the long drug-war nightmare will finally be over.
It has never happened, More important, it will never happen. And to believe it will happen is, well, sheer idiocy. There is a simple reason why victory is impossible in the drug war: the laws of supply and demand. Although the members of Congress, having heard of the laws of supply and demand, oftentimes think they can be repealed by Congress, that’s just more idiocy. That’s because these laws are natural laws, not man-made laws. Like the law of gravity, the laws of supply and demand cannot be repealed by the members of Congress.
