Abstract original: The 2015 National Drug Threat Assessment (NDTA) is a comprehensive assessment of the threat posed to the United States by the tracking and use of illicit drugs. The drug section of this report is arranged in ranking order based on the level of threat each drug presents. The threat level for each drug is determined by strategic analysis of the domestic drug situation during 2014, based on law enforcement, intelligence, and public health data available for the period. For instance, each day in the United States, over 120 people die as a result of a drug overdose. In particular, the number of deaths attributable to controlled prescription drugs (CPDs) has outpaced those for cocaine and heroin combined.
