Officials have uncovered a new synthetic opioid stronger than fentanyl spreading through the illicit drug supply and killing people before many communities even know it exists. The opioid crisis now has a new front-line threat: cychlorphine, a powerful synthetic orphine. Federal officials now sound the alarm for the first time with an emergency drug threat notice.

The White House Office of National Drug Control Policy (ONDCP) issued its first official Drug Threat Notice to warn law enforcement, public health officials, and medical providers about the spread of cychlorphine. Cychlorphine is linked to at least 55 deaths nationwide between 2025 and 2026. For anyone with opioid addiction or for families worried about a loved one, this is a development that demands immediate attention.

The Opioid Crisis Thus Far

Cychlorphine’s formal name is N-Propionitrile Chlorphine and has been detected in the illicit drug supply across 10 states, with the highest concentrations reported in Ohio, Texas, and Tennessee. The Knox County Regional Forensic Center in Tennessee linked the substance to at least 41 fatalities between July 2025 and February 2026 alone.

Those numbers, while devastating, almost certainly undercount the true toll, given cychlorphine’s near-invisibility in standard screening.

Cychlorphine is More Dangerous Than Fentanyl

ONDCP warned that cychlorphine has up to 10x the potency than fentanyl, and overdoses may require multiple doses of naloxone to reverse. Officials also noted the drug is especially difficult to detect because it doesn’t appear on common test strips or hospital opioid urine screenings.

That last detail is critical for anyone in recovery or anyone who uses fentanyl test strips as a harm reduction measure: those strips will not detect cychlorphine. This is a fundamental shift in the opioid crisis landscape that affects not just people actively using substances, but emergency responders, family members carrying naloxone, and treatment providers.

Officials have found cychlorphine mixed with fentanyl, methamphetamine, cocaine, bromazolam, and other illicit substances in addition to pure samples. The opioid belongs to a class of synthetic orphines that include brorphine, chlorphine and spirochlorphine.

Synthetic Opioids and Overdose Risk

Synthetic opioids are man-made substances designed to mimic the effects of naturally derived opioids like heroin or morphine but are engineered to be far more potent. Fentanyl has long been the dominant driver of overdose deaths in the United States and is itself a synthetic opioid roughly 100x more potent than morphine.

The emergence of cychlorphine doesn’t mean fentanyl has receded. In fact, cychlorphine has been found mixed with fentanyl and even vapes. A person who believes they’re using one substance may unknowingly encounter two deadly synthetic opioids simultaneously. Poly-drug combos dramatically increase overdose lethality and complicate emergency response.

ONDCP urged EMS personnel, clinicians, law enforcement and the public to be aware of the drug’s growing presence, prepare for more severe overdose responses and seek immediate medical care in suspected overdose cases.

The White House’s Response

The warning comes just weeks after ONDCP released the 2026 National Drug Control Strategy. This sweeping federal roadmap will disrupt illicit drug trafficking, target transnational criminal organizations and improve detection of emerging synthetic drug threats. Released May 4 by ONDCP Director Sara Carter, the strategy calls for expanded advanced technology to identify evolving drug threats. The program will increase intelligence-driven interdictions of precursor chemicals and nationwide wastewater testing to provide near real-time data on illegal drug trends.

The new Drug Threat Notices can at least inform communities and frontline responders about emerging substances before they become more widespread.

Harm Reduction and Treatment for Opioid Addiction

If you or someone you love has a narcotic addiction, don’t wait and see. The opioid crisis has evolved faster than individual awareness, and professional treatment saves lives.

• Naloxone / Narcan: Given that cychlorphine may require multiple doses, anyone at risk or near someone at risk should carry naloxone and know how to administer doses while calling 911. Narcan nasal spray is available without a prescription, and many local health departments distribute it for free.

• Medication-assisted treatment (MAT): Evidence-based opioid addiction treatment, including buprenorphine, methadone, and naltrexone, dramatically reduces overdose death risk.

• Narcotics Anonymous (NA) Meetings: Peer support through Narcotics Anonymous is a proven component of long-term recovery from narcotic addiction. NA meetings exist in nearly every city and town in the country, in-person and online.
