Justice Against Sponsors of Illicit Fentanyl Act of 2023

This bill allows U.S. citizens injured by fentanyl trafficking to sue foreign governments or entities in U.S. courts for knowingly providing material support to fentanyl traffickers. It targets foreign actors - such as governments or companies - that supply precursors or resources used to produce illicit fentanyl, directly affecting those who enable trafficking networks. The law creates a new civil liability pathway, requiring plaintiffs to prove the foreign entity acted "knowingly or recklessly," not merely negligently. It applies to cases involving fentanyl-related harm since 2013, with limited court jurisdiction for such claims.
