Which agency must HSI deconflict with when investigating Title 21 drug cases?

HSI must deconflict with the DEA when investigating Title 21 drug cases because the DEA is the primary federal agency responsible for enforcing laws related to controlled substances in the United States. Title 21 of the United States Code deals specifically with drug enforcement and regulation. The DEA coordinates national efforts to combat drug trafficking and abuse, making it crucial for HSI to collaborate and ensure that there is no overlap or conflict in their investigations. This helps to streamline operations, share intelligence, and improve the overall effectiveness of drug enforcement efforts, ensuring that action against drug-related crimes is both comprehensive and efficient.
