Assumed to be fentanyl

4 major substances detected:

  • erythritol
  • 4-ANPP
  • fentanyl
  • phenethyl 4-ANPP

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.
