 | The latest analogue to hit the streets is called U-47700 and has street names such as Pink or Pinky. Officials said it has been tied to 46 deaths. U-47700 is an opioid analgesic drug developed by Upjohn in the 1970s. It acts as a selective agonist of the µ-opioid receptor. U-47700 is thought to be 7.5x the potency of morphine. It was derived from an earlier opioid AH-7921. |  |
 | U-47700 has never been used medically, only in research, nor has it been tested on humans, until now. Responding to the imminent threat to public health and safety, the U.S. Drug Enforcement Administration has placed U-47700 into Schedule 1 of the Controlled Substances Act, effective November 14, 2016. Currently numerous sources can be found on the internet without difficulty. It can be had for as little as $ 7.28 per gram if buying a kilo. |  |
