Map 6. Principal drug distribution centers.
U.S. map showing cities and areas serving as principal drug distribution centers, broken down by drug.

Principal Distribution Centers (PDCs) were identified primarily through analysis of domestic drug seizure data; however, law enforcement reporting also was considered. Analysis of EPIC data from 2000 through 2004 revealed the cities that were most often identified as the origin or destination of seized drug shipments. These cities constitute most of the identified PDCs. Other cities, however, were included based on law enforcement reporting that indicates these cities are likely as significant as other PDCs, despite somewhat lower associated drug seizures.
