818296

From Peoria, Illinois on August 10, 2026

Assumed to be heroin

Only 1 major substance detected:

  • diphenhydramine

But we found lots of contaminants too, with traces of methamphetamine + pending identification + clonazolam + metonitazene + N-desethyl etonitazene + pending nitazene + N-pyrrolidino-metonitazene + N-propionitrile chlorphine + N-pyrrolidino-protonitazene. Trace substances in small quantities are usually harmless but can sometimes cause health problems. Unexpected sensations may be due to these. The trace designation indicates the conclusive identification of the substance at a relatively low abundance compared to the sample's primary component(s). A substance is designated as "trace" when the peak height is less than 5% of the height of the most abundant peak detected in the sample.
