Furanylfentanyl review
Furanylfentanyl (Fu-F) is an opioid analgesic that is an analog of fentanyl and has been sold as a designer drug. It has an ED50 value of 0.02 mg/kg in mice. This makes it approximately five times less potent than fentanyl.

Side effects
Side effects of fentanyl analogs are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening. Fentanyl analogs have killed hundreds of people throughout Europe and the former Soviet republics since the most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear.
Life-threatening adverse reactions caused by furanylfentanyl use have been observed in Sweden and Canada. At least seven deaths in Cook County, Illinois, have been linked to furanylfentanyl in 2016, with additional deaths in suburban Chicago in 2017.
Legal status
Furanylfentanyl is illegal in Sweden as of January 2016.
The United States Drug Enforcement Administration (DEA) proposed a temporary placement of furanylfentanyl into Schedule I of the Controlled Substances Act on 27 September 2016. On November 29th, 2016, the DEA issued its final rule, making furanylfentanyl Schedule I.
The China connection
According to the DEA, fentanyl and its analog are being mass-produced in clandestine labs in China and are then smuggled into the United States via traditional distribution routes through Mexico. These new variants of fentanyl are manufactured by Chinese chemists in order to circumvent restrictions on sale of fentanyl in the United States.
