605264

From Pittsburgh, Pennsylvania on May 11, 2026

Assumed to be fentanyl

4 major substances detected:

  • lidocaine
  • medetomidine
  • tetracaine
  • 6-monoacetylmorphine (6-MAM)

But we found lots of contaminants too, with traces of acetaminophen + caffeine + melatonin + acetylcodeine + heroin + fentanyl + bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate + xylazine. 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.

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.
