300757

From Asheboro, North Carolina on November 1, 2022

Assumed to be heroin

3 major substances detected:

  • nicotine
  • 4-ANPP
  • fentanyl

But we found lots of contaminants too, with traces of methamphetamine + niacinamide + diphenhydramine + p-fluorofentanyl + phenethyl 4-ANPP. 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.
