815436
From Bronx, New York on December 24, 2025
Assumed to be fentanyl
2 major substances detected:
- caffeine
- procaine
And we also found traces of medetomidine + 4-ANPP + fentanyl. Trace substances in small quantities are usually harmless, but can sometimes cause health problems. Unexpected sensations may be due to these.
There were just traces of fentanyl. This could have been contamination, like if drugs were stored in old bags. But since fentanyl is so potent you should be prepared. Consider getting fentanyl test strips online or from a harm reduction program if you weren't expecting it. Carry naloxone (Narcan) to reverse overdoses. Even traces of fentanyl could be a problem if you don't use opioids regularly. Don't use alone so someone can help if you go out.
