Urgent warning as drug 10 times more powerful than fentanyl claims first LA victim
Key Points:
- Los Angeles health authorities have issued an urgent warning about cychlorphine, a synthetic opioid 10 times more potent than fentanyl, after it caused its first fatality in LA County in February.
- The drug has also been linked to a fatal overdose in San Francisco in April, marking its first detection there, and is currently undetectable by fentanyl testing strips.
- Cychlorphine has been present in the US drug supply since 2024, found in 19 states, and can appear in various forms including liquids, powders, crystals, and counterfeit pills.
- The DEA classified cychlorphine as a Schedule I drug in August 2026, making possession and sale illegal, while authorities warn it is often mixed into street drugs without users' knowledge.
- Health officials recommend never using drugs alone, avoiding mixing substances, and carrying naloxone, a medication that can reverse opioid overdoses and save lives.
