The global war on drugs has failed. When the United Nations Single Convention on Narcotic Drugs came into being 50 years ago, and when President Nixon launched the US government’s war on drugs 40 years ago, policymakers believed that harsh law enforcement action against those involved in drug production, distribution and use would lead to an ever-diminishing market in controlled drugs such as heroin, cocaine and cannabis, and the eventual achievement of a ‘drug free world’. In practice, the global scale of illegal drug markets – largely controlled by organized crime – has grown dramatically over this period. While accurate estimates of global consumption across the entire 50-year period are not available, an analysis of the last 10 years alone shows a large and growing market.
