"The South Texas High Intensity Drug Trafficking Area (HIDTA) region has a growing influence on domestic drug availability as evidenced by the large and increasing quantities of marijuana and heroin seized in the region the past year, a large percentage of which is destined for drug markets throughout the United States. Marijuana seizures in the region increased 59 percent during the most recent reporting period, from 580,753 kilograms in 2009 to 924,732 kilograms in 2010, while heroin seizures increased 260 percent from 101 kilograms in 2009 to 364 kilograms in 2010.1 Mexican drug trafficking organizations (DTOs) are the primary smugglers of these drugs, as well as the cocaine and methamphetamine that are either distributed in or transit the region. Within the region, marijuana is a principal drug threat, followed closely by cocaine. Key issues identified in the South Texas HIDTA region include the following: 1) Mexican marijuana seizures increased significantly in the South Texas HIDTA region in 2010--resulting in increased marijuana flow through the region to drug markets in Texas, the Midwest, the East, and the Southeast. 2) The total amount of heroin seized in the South Texas HIDTA region increased significantly over the past year and prices declined, indicating increased availability of the drug. 3) Mexican DTOs, the dominant organizational drug threat to the South Texas HIDTA region, are employing gang members to distribute drugs and conduct other criminal activity on their behalf."
