"This report provides an overview of U.S. international drug control policy. It describes major international counternarcotics initiatives and evaluates the broad array of U.S. drug control policy tools currently in use. The report also considers alternative counter-drug policy approaches to international drug control initiatives and raises several counter-drug policy issues and considerations for policy makers. Illegal drugs refer to narcotic, psychotropic, and related substances whose production, sale, and use are restricted by domestic law and international drug control agreements. The most common illegal drugs include cannabis, cocaine, opiates, and synthetic drugs. International trade in these drugs represents a lucrative and what at times seems to be an intractable criminal enterprise, affecting countries worldwide and generating between $100 billion and $1 trillion in illicit profits per year. Revenue from the illegal drug industry provides international drug trafficking organizations with the resources to evade and compete with law enforcement officials; penetrate legitimate economic structures through money laundering; and, in some instances, challenge the authority of national governments."
