Cychlorphine Surfaces in Ohio in 36 Cases, Outpacing Fentanyl Potency
2 articles · Updated · WOWO · Jul 14
Summary
Ohio investigators have detected the synthetic opioid cychlorphine 36 times since last October, marking the arrival of a drug researchers say is more potent than fentanyl.
Dr. Jon Sprague said the drug is part of a new “orphine” class that can release more dopamine than other opioids and may require several naloxone doses—or in some cases resist reversal.
Hamilton County provided an early warning last fall when a man who thought he bought Xanax overdosed on a mix containing cychlorphine, fentanyl and xylazine; he survived after multiple naloxone doses.
Chinese chemists began manufacturing orphines after nitazenes were banned last year, Sprague said, helping explain why the compounds first appeared in the U.S. last fall.
Ohio is so far the only state to automatically treat orphines as controlled substances because its pharmacophore rule makes fentanyl-like core structures illegal.

Overview
Cychlorphine is a new and extremely potent synthetic opioid that first appeared in the U.S. illicit drug market around 2024. By early 2026, it was linked to at least 41 deaths across 13 states, raising urgent public health concerns. Cychlorphine is about 10 times stronger than fentanyl and can be fatal even in microscopic doses, especially since users often do not know it is present or how strong it is. It is frequently mixed with other drugs and cannot be detected by standard fentanyl test strips, making accidental overdose more likely. Overdoses are hard to reverse, often requiring multiple doses of naloxone, prompting urgent warnings from health authorities.
