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.
PDCs for cocaine are Phoenix, Arizona; Los Angeles, California; Denver, Colorado; Miami, Florida; Atlanta, Georgia; Chicago, Illinois; Detroit, Michigan; Kansas City and St. Louis, Missouri; New York, New York; Philadelphia, Pennsylvania; Dallas/Fort Worth, El Paso, Houston, and South Texas; and San Juan, Puerto Rico
PDCs for heroin are Los Angeles, California; Miami, Florida; Chicago, Illinois; St. Louis, Missouri; New York, New York; and Philadelphia, Pennsylvania.
PDCs for methamphetamine are Phoenix, Arizona; the Central Valley, Los Angeles, San Diego and San Francisco, California; Denver, Colorado; Atlanta, Georgia; Honolulu, Hawaii; Des Moines, Iowa; Kansas City, Missouri; Las Vegas, Nevada; and Yakima Valley, Washington.
PDCs for marijuana are Phoenix and Tucson, Arizona; the Central Valley, Los Angeles, and San Diego, California; Atlanta, Georgia; Chicago, Illinois; Detroit, Michigan; New York, New York; Dallas/Fort Worth, El Paso, Houston, and South Texas; and Seattle Washington.
