811163
From King County, Washington on April 29, 2025
Assumed to be fentanyl; M30
3 major substances detected:
- acetaminophen
- 4-ANPP
- fentanyl
But we found lots of contaminants too, with traces of caffeine + diphenhydramine + lidocaine + dextromethorphan. 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.

For pills and fake pills, you may see extra peaks on the left hand part of the chromatogram. These represent fillers and trace chemicals from the pill binder. These substances are better isolated using infrared light (FTIR), and GCMS only provides limited information. See note below under 'What we can and can't tell'. Contact us if you want details.
