- Fentanyl also called
- fent, fentanil, carfentanil, nitazene, nitazenes
- Kratom also called
- mitragynine, mitragyna, mitragyna speciosa, krat
Dangerous
Fentanyl sets the risk here and kratom does nothing to blunt it. Kratom's ceiling protects against kratom, not against a full agonist dosed in micrograms. Fentanyl now appears in the majority of kratom-positive overdose deaths, up from about a third in 2018 to over 60% by 2022 — that shift is about the supply, not about kratom.
The risk here is to the body — breathing, heart, temperature or organs. Set limits before you start, because this kind of harm does not announce itself in time to react.
