Illegal drugs threaten the Mexican governance because of the corruption they generate. The Mexican government has been fighting this threat for years in a context of institutional weakness and strong pressures from the United States. The fact that Mexico is a natural supplier of illegal drugs to the biggest market in the world, the United States, puts the Mexican government in a very complex situation with no alternatives other than to continue fighting drugs with very limited institutional and human resources. In this process, Mexico has no margin for maneuver to change the parameters of the war on drugs.
