Fentanyl analogues have killed hundreds of people across Europe and the former Soviet republics since their most recent resumption of use began in Estonia in the early 2000s, and newer derivatives continue to appear.
Life-threatening side effects caused by the use of furanylfentanyl have been observed in Sweden and Canada. At least seven deaths in Cook County, Ill. Were linked to furanylfentanyl in 2016, with additional deaths in suburban Chicago in 2017.
Detection in biological fluids
Furanylfentanyl can be measured in the blood or urine to monitor use, confirm a diagnosis of poisoning, or help with a forensic investigation of death. Commercially available immunoassays are often used as initial screening tests, but chromatographic techniques are generally used for confirmation and quantification. Blood levels of furanylfentanyl are expected to be between 1 and 45 μg / L in fatal overdose victims
