New opioid up to 10 times stronger than fentanyl spreading across US
A powerful new lab-made opioid is moving through the illegal U.S. drug supply, and federal officials warn it could keep spreading.
A new synthetic opioid called cychlorphine is emerging as a major threat in the U.S. drug supply. Up to ten times more potent than fentanyl, cychlorphine is spreading rapidly across the country, appearing in every region and linked to at least 55 overdose deaths in 2025 and 2026 alone. Tennessee has borne the brunt of the crisis, with 41 overdose deaths tied to the drug between July 2025 and February 2026.
Cychlorphine stands apart from fentanyl as it belongs to a newer family of synthetic opioids known as orphines. It can be found on its own or mixed with other drugs, including fentanyl, methamphetamine, cocaine, and sedatives. Disturbingly, cychlorphine may evade detection by standard drug test strips or routine hospital opioid urine screens, potentially leading to underreported fatalities.
Recognizing an overdose can be challenging, as naloxone—a medication used to reverse opioid overdoses—may not be effective against cychlorphine. Emergency response is crucial, with 911 calls necessary if an overdose is suspected. The article urges heightened vigilance, especially among teenagers who may be at risk due to the prevalence of counterfeit pills, either bought online or offered by peers. Awareness and education are vital to combat this emerging opioid crisis.
