603346

From Cadillac, Michigan on May 20, 2025

Assumed to be heroin; fentanyl

This is a messy brew of 8 major substances:

  • acetaminophen

  • caffeine

  • diphenhydramine

  • lidocaine

  • 6-monoacetylmorphine (6-MAM)

  • heroin

  • fentanyl

  • bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate

But we found lots of contaminants too, with traces of N-phenylpropanamide + 4-ANPP + ethyl 4-ANPP + acetylcodeine. 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.

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.
