INDIANA — Health officials in Indiana are on high alert as a dangerous new synthetic opioid, cychlorphine, begins to infiltrate the Midwest drug supply. The Indiana State Department of Health issued a formal warning this week, noting that the substance is estimated to be 10 times more powerful than fentanyl.
The emergence of cychlorphine (scientifically known as N-Propionitrile chlorphine) marks a new and even more lethal chapter in the ongoing synthetic opioid crisis.
While confirmed cases have not yet officially been released, the drug has moved rapidly through neighboring states. Public health data from early 2026 shows a concerning pattern:
- Tennessee: At least 16 overdose deaths in East Tennessee have been linked to the drug since late 2025.
- Kentucky: The Kentucky Office of Homeland Security issued an alert in February after the drug was detected in central parts of the state.
- Ohio: The Hamilton County Addiction Response Coalition in Cincinnati began tracking the substance as it appeared in complex “street mixes.”
Why Cychlorphine is Different
Cychlorphine belongs to a class of chemicals known as “orphines.” Experts warn that its chemical structure makes it particularly difficult for traditional harm-reduction tools to catch.
Unlike many other synthetic opioids, cychlorphine cannot be detected by standard fentanyl test strips.
Officials warn that an amount smaller than a grain of salt can be fatal.
Because it is often mixed into powders or pressed into counterfeit pills, many users are completely unaware they are consuming it.
“When individuals in active use are more tolerant to fentanyl… manufacturers find a cheaper way to produce the same euphoric high,” explained Brianna Hicks of Overdose Lifeline. “Individuals may not know that they’re actually ingesting it.”
The Response: Naloxone and Narcan
Despite the drug’s extreme potency, health leaders emphasize that Naloxone (Narcan) remains the most effective tool for reversing an overdose. However, there is a critical caveat for cychlorphine.
Because the drug binds so strongly to the brain’s opioid receptors, a single dose of Narcan may not be enough. First responders and bystanders are being advised that multiple doses of the reversal agent may be required to restore a person’s breathing.
The Indiana Department of Health are urging Hoosiers to exercise extreme caution.
- Assume Polysubstance Use: Most street drugs in 2026 are “cocktails” containing multiple synthetics like xylazine, fentanyl, and now orphine analogues.
- Carry Naloxone: It is available without a prescription at pharmacies across Indiana and through local health departments.
- Call 911 Immediately: If you suspect an overdose, call for professional medical help even if Narcan has been administered.
