"The illicit trafficking and abuse of drugs present a challenging, dynamic threat to the United States. Overall demand is rising, largely supplied by illicit drugs smuggled to U.S. markets by major transnational criminal organizations (TCOs). Changing conditions continue to alter patterns in drug production, trafficking, and abuse. Traffickers are responding to government counterdrug efforts by modifying their interrelationships, altering drug production levels, and adjusting their trafficking routes and methods. Major Mexican-based TCOs continue to solidify their dominance over the wholesale illicit drug trade as they control the movement of most of the foreign-produced drug supply across the U.S. Southwest Border."
