604827

From Wayne, Michigan on May 8, 2026

Assumed to be fentanyl, xylazine

3 major substances detected:

  • medetomidine
  • 4-ANPP
  • fentanyl

And we also found traces of caffeine. Trace substances in small quantities are usually harmless, but can sometimes cause health problems. Unexpected sensations may be due to these.

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.
