A new synthetic drug believed to be 10 times more potent than fentanyl has been linked to dozens of deaths in Tennessee, with a growing number of fatalities reported in states across the U.S.
The drug, N-Propionitrile chlorphine was first detected in toxicology from postmortems in mid-2024 by the Center for Forensic Science Research and Education, in Horsham, Pennsylvania, and since then its use appears to have exploded.
