About Nitazenes
Nitazenes are highly potent synthetic opioids that have appeared as adulterants in illicit drug supplies. They are not part of the standard 5-, 10- or 12-panel or DOT tests.
Standard opiate and fentanyl screens usually do not detect them; a dedicated mass-spectrometry assay is required.
Because they are extremely potent, detection and clinical response are specialised areas — this is a medical and public-safety concern rather than a routine testing one.
