Carfentanyl has been a thing here on Long Island for a few years now. The whole Heroin/Fentanyl thing is an epidemic in both Nassau & Suffolk Counties. Personally, I didn't even know it was possible to illegally sell fentanyl until about a few years ago. Fentanyl is usually prescribed in patches, so I couldn't figure out how people were selling this shit. Then someone actually told me how there's a way to melt the Fentanyl itself out of the patch itself. Some real chemistry shit.
