"Given the strategic importance of reducing drug production and trafficking in the Andean countries—the source of more than 95 percent of the cocaine seized in the United States and much of the heroin available east of the Mississippi River—accurate and reliable information on the results of this assistance is essential. State, USAID, and DEA have reported the required information, with attestations of its reliability, regarding the combined $4 billion in assistance that they provided in fiscal years 2006 through 2011. However, lacking attestations by DOD’s IG, ONDCP has minimal assurance of the reliability of DOD’s reporting on its estimated $956 million in counternarcotics assistance in those years. Without reliable information, ONDCP may be limited in its ability to carry out its responsibility for coordinating and overseeing implementation of the policies, goals, objectives, and priorities established by the national drug control program and to report accurately to Congress on counternarcotics assistance provided by agencies under ONDCP’s purview. Moreover, without reliable information, Congress and other decision makers, including ONDCP, may lack information that is essential to assessing progress toward the U.S. goal of curtailing illicit drug consumption in America, making decisions on the allocation of resources, and conducting effective oversight."
