The purpose of this legislation, known as the Measuring Illicit Fentanyl Trafficking Act, is to enhance the efforts of the Department of Homeland Security in combating the trafficking of illicit fentanyl. The act aims to improve the detection, deterrence, and seizure of this dangerous substance, which has been a significant contributor to the opioid crisis. Key provisions of the act require the Secretary of Homeland Security to take specific actions within one year of the law's enactment.
