809968

From Hamilton County, Ohio on October 22, 2025

Assumed to be fentanyl

Only 1 major substance detected:

  • methamphetamine

But we found lots of contaminants too, with traces of diphenhydramine + medetomidine + cocaine + fentanyl + 4-ANPP + lidocaine + N-propionitrile chlorphine. 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.

There were just traces of fentanyl. This could have been contamination, like if drugs were stored in old bags. But since fentanyl is so potent you should be prepared. Consider getting fentanyl test strips online or from a harm reduction program if you weren't expecting it. Carry naloxone (Narcan) to reverse overdoses. Even traces of fentanyl could be a problem if you don't use opioids regularly. Don't use alone so someone can help if you go out.
