Joe Rogan Experience #2567 - Mariana van Zeller · Aired Oct 16, 2026
Claim summary · not a verbatim quotation
There's a new drug called nitazenes that is 50 times more powerful than fentanyl, Narcan sometimes doesn't work on it, and it doesn't show up in test strips.
The finding
What the evidence shows
Mariana describes nitazenes as one new drug with a single potency ratio. CDC documents an older opioid class whose potency varies by analogue. Naloxone has reversed nitazene-involved overdoses, although repeated doses may be needed; her word sometimes does not mean it always fails. Ordinary fentanyl strips cannot be assumed to identify a different opioid class.
