"Louisiana's geographical location makes it an important transshipment point for illegal drugs destined for the southeast, northeast, and to a lesser extent, the midwest. Mexican and Colombian drug trafficking organizations use Louisiana's extensive coastline, seaports, interstate highways and remote airstrips to transport drugs into Louisiana and the United States. Louisiana's increasing prison population and high rates of violent crime both have roots in drug distribution and abuse. Wholesale and retail distributors take advantage of the proximity of Houston, a major drug distribution center, to make frequent trips to purchase cocaine and marijuana. Highly organized criminal groups, normally African American, Asian, and Caucasian, are involved in the wholesale distribution of cocaine and marijuana. They use close ties to Mexican criminal groups in South Texas to facilitate their operations. Street gangs dominate retail distribution of cocaine, heroin, and marijuana in larger cities and towns, and are increasingly moving into Louisiana's rural communities where local, independent dealers traditionally serviced drug markets. Most major cities in Louisiana are experiencing an increase in street gang activity. The distribution and abuse of crack cocaine and the widespread availability of powdered cocaine are the primary illegal drug threats in Louisiana. "
