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. Research done in the 1980's showed that in humans furanylfentanyl is 50-100 times more potent than morphine, making it roughly half as potent as fentanyl, toxicology reports seem to confirm this finding after furanylfentanyl began appearing on the illicit drug market in 2015.
