America faces another ongoing public health challenge – outside of Covid-19 – in the scourge of illicit opioids getting across our borders through the U.S. Postal Service (USPS). Congress passed, and President Donald J. Trump signed, the bipartisan STOP Act in 2018 to combat synthetic drugs like fentanyl and carfentanil from being shipped right into the United States. The Department of Homeland Security has released the interim final rule (IFR) titled the “Mandatory Electronic Information for International Mail Shipments” to implement the STOP Act, yet that draft has alarming loopholes that will allow opioids to continue to be shipped right into the United States via the U.S. Postal Service.
