President Nixon declared war on public enemy number one in 1971. By 1994, drug laws resulted in the incarceration of one million Americans each year. The US now spends $50 billion annually on the war on drugs, mainly focussed on reducing supply " often through military aid. Comparatively little is spent on treatments for addicts. It was recently estimated that the legalisation of drugs would bring annual savings on enforcement and incarceration of about $41 billion, and also raise $47 billion in tax. So who, if anyone, is benefitting from the war on drugs?
