A Knoxville medical examiner uncovered a deadly new opioid crisis when Dr. Darinka Mileusnic-Polchan identified cychlorphine, a compound 10 times more powerful than fentanyl. Since October 2025, the region has seen at least 50 fatal overdoses from this drug, which has quickly become the third-most-common cause of overdose deaths in the area.

The discovery highlights how medical examiners have evolved into frontline drug detectives as novel opioids infiltrate communities nationwide. Many labs lack the resources to identify these compounds, leading to underreporting. Knoxville has emerged as a national hot spot for orphines, with 11 orphine variations now identified globally.

Research suggests these drugs originate in Chinese labs following bans on earlier synthetic opioids. The situation presents significant challenges for public health officials and law enforcement. Dr. Mileusnic's persistence in identifying cychlorphine demonstrates how forensic medicine plays a crucial role in combating the evolving opioid crisis, though resources remain strained for medical examiners nationwide.
