816788
From Durham, North Carolina on March 13, 2026
Assumed to be fentanyl, xylazine
3 major substances detected:
- caffeine
- cocaine
- fentanyl
But we found lots of contaminants too, with traces of dimethyl sulfone (methylsulfonylmethane MSM) + erythritol + gabapentin + lidocaine + medetomidine + 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.
