The Strengthening Sanctions on Fentanyl Traffickers Act of 2025 aims to enhance the United States' capacity to combat the international trafficking of illicit drugs, particularly fentanyl and its precursors. The legislation focuses on imposing sanctions against individuals and entities, especially companies from China, that contribute to this trafficking. By doing so, it seeks to address the growing opioid crisis linked to fentanyl and improve public health outcomes.
