The 2014 NDTA Summary uses information provided by 1,226 state and local law enforcement agencies through the 2014 National Drug Threat Survey (NDTS). At a 95 percent confidence level, the 2014 NDTS results are within 2.59 percentage points of the estimates reported. NDTS data used in this report do not imply that there is only one drug threat per state or region or that only one drug is available per state or region. A percentage given for a state or region represents the proportion of state and local law enforcement agencies in that state or region that identified a particular drug as their greatest threat or as available at low, moderate, or high levels.
