Quick Summary

Los Angeles authorities are issuing urgent warnings about cychlorphine, a drug 10 times more potent than fentanyl, after its first fatal overdose victim was reported in the city. The drug has been detected in 19 states since 2024 and was recently classified as a Schedule I substance by the DEA in August 2026. Health officials caution that cychlorphine can be mixed into various street drugs undetectably, making it extremely dangerous for users to identify or avoid.

Story summary

Cyclophanilidine, a super-drug 10 times more potent than fentanyl, claimed its first victim in Los Angeles in October 2026. San Francisco health officials had previously linked cyclophanilidine to a fatal overdose in April, marking the drug's first detection in that city. Officials warn that the drug is being mixed into illicit supplies without users' knowledge and is undetectable by standard fentanyl testing strips. Since its appearance in the US drug supply in 2024, cyclophanilidine has been identified in 19 states. The DEA classified it as a Schedule I drug in August 2026, making possession or sale illegal. Due to its ability to be hidden across various street drugs like liquids, rocks, powders, and counterfeit tablets, detection is extremely challenging.
