Tennessee Becomes Ground Zero
The Tennessee Department of Health confirmed in March 2026 that more than 30 people have died from cychlorphine-related overdoses since October 2025. The deaths are concentrated across eight East Tennessee counties, with Knox County seeing the highest number of fatalities.
How It Was Discovered
The Knox County Regional Forensic Center first identified cychlorphine in a Roane County overdose death in late November 2025. An earlier Knox County case was later traced back to October 2025. By mid-January 2026, nine deaths from the October-December period had been confirmed, with seven additional deaths bringing the total to 16.
By February 5, 2026, the Knox County Regional Forensic Center publicly announced the 16 deaths. Within weeks, the statewide total climbed past 30, with forensic experts warning that the rate of deaths was doubling.
Mixed With Other Drugs
All 16 initially confirmed deaths involved mixtures with other substances, primarily methamphetamine and fentanyl. This means many users had no idea they were consuming cychlorphine. The drug was not sought by name - it entered the supply as an invisible adulterant.
State Response
The Tennessee Bureau of Investigation is actively tracking suppliers and distribution networks. The Tennessee Department of Health has issued public warnings emphasizing that standard fentanyl test strips cannot detect cychlorphine and that naloxone may require multiple doses.
If you or someone you know is at risk, call 988 (Crisis Lifeline) or the Tennessee REDLINE at 1-800-889-9789.
