812861

From Fayetteville, North Carolina on July 11, 2025

Assumed to be fentanyl

2 major substances detected:

  • 4-ANPP
  • fentanyl

But we found lots of contaminants too, with traces of phenethyl 4-ANPP + acetyl fentanyl + ethyl 4-ANPP + cocaine + N-phenylpropanamide. 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.
