604532

From Asheboro, North Carolina on May 2, 2026

Assumed to be heroin, fentanyl, xylazine, medetomidine

This is a messy brew of 7 major substances:

  • erythritol
  • acetaminophen
  • xylazine
  • 4-ANPP
  • despropionyl ortho-methylfentanyl
  • fentanyl
  • ortho-methylfentanyl

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.

Xylazine causes serious skin problems. These can happen anywhere on the body and don't heal quickly. And, xylazine can come on stronger than traditional dope and knock you out, so be mindful of your surroundings. It's best to avoid dope with xylazine. You might need medical attention to prevent long-term damage.

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.
