Latin America is now at the vanguard of international efforts to promote drug policy reform: Bolivia has rewritten its constitution to recognize the right to use the coca leaf for traditional and legal purposes, Uruguay has become the first nation in the world to adopt a legal, regulated Cannabis market, and Colombia, Mexico, Guatemala, and Ecuador are openly critiquing the prevailing international drug control paradigm at the UN. And now with the United States itself relaxing its marijuana laws state by state, the U.S. prohibitionist drug war strategies are losing credibility in the region.

Latin America has emerged at the vanguard of efforts to promote debate on drug policy reform. For decades, Latin American governments largely followed the drug control policies and programs of Washington’s so-called war on drugs. Yet two parallel trends have resulted in a dramatic change in course: the emergence of left-wing governments that have challenged Washington’s historic patterns of unilateralism and interventionism and growing frustration with the failure of the prohibitionist drug control model put forward by the US government.
