This bill amends the Office of National Drug Control Policy Reauthorization Act of 1998 to strengthen federal efforts against drug trafficking by mandating a comprehensive Caribbean Border Counternarcotics Strategy . This strategy is designed to prevent the illegal flow of drugs through the Caribbean region into the United States, encompassing all entry points and air and maritime approaches, while also promoting legitimate trade and travel. The strategy must clearly define the roles and responsibilities of relevant National Drug Control Program agencies and identify the specific resources needed for its implementation. It also expands the definition of "drug control" to explicitly include activities aimed at mapping, tracking, dismantling, and disrupting the financial networks of drug trafficking and money laundering organizations. Additionally, the bill clarifies the geographical definitions of "State" and "United States" to include territories and possessions. Crucially, the strategy must include specific provisions for Puerto Rico and the United States Virgin Islands , focusing on preventing drug trafficking to or through these territories and substantially reducing drug-related violent crime. It also requires recommendations for additional assistance or authorities needed by Federal, State, and local law enforcement agencies in these areas, including an evaluation of existing support and infrastructure deficiencies.
