814791

From Espanola, New Mexico on September 18, 2025

Assumed to be fentanyl

4 major substances detected:

  • acetaminophen
  • lidocaine
  • fentanyl
  • bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate

And we also found traces of 4-ANPP. 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.

Fentanyl is potent and the amount changes by batch. If you weren't expecting it, consider getting test strips online or from a harm reduction program. Carry naloxone (Narcan) to reverse overdoses. Don't use alone so someone can help if you go out.

There are a lot of different substances in this sample. We don't know the harms that some of these can cause. Be careful and be prepared for unexpected reactions.

Looks = white, fine, chunky, powder
