Assumed to be fentanyl
This is a messy brew of 5 major substances:
- caffeine
- medetomidine
- cocaine
- 4-ANPP
- fentanyl
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.
