Where did the regulatory underpinnings for the global drug wars come from? This book is the first fully-focused history of the 1961 UN Single Convention on Narcotic Drugs, the bedrock of the modern multilateral drug control system and the focal point of global drug regulations and prohibitions. Although far from the propagator of the drug wars, the UN enabled the creation of a uniform global legal framework to effectively legalise, or regulate, their pursuit. This book thereby answers the question of where the international legal framework for drug control came from, what state interests informed its development and how complex diplomatic negotiations resulted in the current regulatory system, binding states into an element of global policy uniformity.
