The logics of the European Union’s policy and practices against narcotic drugs in Latin America and the Caribbean (LAC) have undergone a substantial shift the past decade: from development to security. Based on an empirical mapping of the EU’s drug-related projects in LAC, this article argues that an ‘integrated and balanced’ approach to drugs policy is being replaced by a bifurcation between the broader domains of development policy and security policy. Questions are raised as to how the EU’s projects on development and security might counteract one another, and how the Union’s programme aimed at dismantling transnational organized crime along the cocaine trafficking routes to Europe might have unintended consequences. While keeping in mind the shifting tectonics of the international drug prohibition consensus, the article goes on to analyze the increasingly salient security rationale in EU external drugs policy against the backdrop of the EU’s emerging role as a global security actor. In doing so, it touches upon the intrinsic tensions between human rights and (supra) national security.
