Live Report of Samples Received by UNC

This live report lists all samples containing the nitazene class of synthetic opioids analyzed by the UNC Street Drug Analysis lab.

As a class, relatively little is known about nitazenes in humans. Some are potent opioids (mu receptor agonists), and other nitazenes are weaker than typical synthetic opioids on the street. Naloxone is believed to be effective against most nitazenes studied at the current time.

Some of the nitazenes with longer chemical names (starting with N- or a number) may be leftover starting materials from the synthesis process, and others may be breakdown products from GCMS analysis.

📍 A note on geography. Seeing more samples from one location doesn't mean that that location is seeing more of this substance than other places. These are early days, and programs are preferentially sending us samples that they think might contain unexpected or novel opioids. The widespread nature of the substance does provide clues about the extent of its distribution. There are plenty of places we don't get samples from, so not seeing a location on this list doesn't mean nitazenes are not present locally.

Sensations Reported in situ

Sensations reported for samples that also contained carfentanil. Nearly all samples contained other psychoactive substances, so this does not represent sensations specific to nitazenes, but rather sensations in situ with other substances in the real world drug supply.
