A lab-made opioid with a tricky name and deadly punch is creeping into the illicit drug supply, and federal agents in El Paso say the border region needs to pay attention.
The Drug Enforcement Administration’s El Paso office warned Tuesday that “ciclorfina” – the Spanish name for an emerging synthetic opioid also called cychlorphine – is appearing in the drug market and can be lethal. DEA El Paso spokesman Carlos Briano discussed the threat in an interview with local reporter Carlos Álvarez of ElPasoYa, a conversation the division later shared publicly.
What forensic labs are finding
Forensic scientists report that the compound, formally N-propionitrile chlorphine, belongs to an emergent subclass of synthetic opioids sometimes called “orphines.” Early laboratory pharmacology suggests it may be roughly ten times as potent as fentanyl. The Center for Forensic Science Research and Education issued a public alert describing multiple positive blood specimens from fatal overdoses and a recent rise in tentative identifications at commercial labs, according to CFSRE.
Federal testing has started to pick up the drug across the United States. The DEA told reporters that N-propionitrile chlorphine was first reported by a DEA laboratory in Florida in April 2024 and that DEA laboratories had identified the substance in 22 samples through the end of February 2026, as reported by The Hill via Yahoo. Local forensic centers in Tennessee also linked a cluster of deaths to the compound, reporting 16 fatalities in one East Tennessee region, according to 16 overdose deaths in one East Tennessee region, as per Hoodline.
Why El Paso should pay attention
El Paso sits on a major trafficking corridor where fentanyl and counterfeit pills routinely move across the border, so the arrival of an even more potent opioid could raise local overdose risk. The DEA’s national enforcement work, in which the El Paso Field Division has played a prominent role, helped seize millions of lethal doses in a record operation announced in May 2025. That context underscores why new synthetic opioids are a particular concern for border communities. In its social post promoting the local interview, the agency highlighted that ciclorfina “could cause death.”
How to stay safer
Public-health and harm-reduction groups emphasize familiar but vital precautions: never use alone, carry naloxone, and call 911 immediately in a suspected overdose. The CDC advises administering naloxone and seeking emergency care while supporting breathing and positioning the person to protect their airway, according to the CDC. Experts tracking the compound also warn that standard fentanyl test strips may not detect cychlorphine and that its extreme potency could mean multiple naloxone doses are needed to revive someone, per CFSRE…
