U-47700 is an illegal synthetic opioid. It’s a Schedule I controlled because it has no medical purpose and is highly addictive.
Also called “pink,” or “pink heroin,” U-47700 was created as an experiment in the 1970s by a company trying to find a less addictive opioid painkiller. Today, it’s available on the street and the dark web as a light pink powder, nasal spray, or pill.
