Information from seizures suggests that cyclopropylfentanyl may have also been sold on the illicit opioid market as methoxyacetylfentanyl, as heroin and in mixtures with other opioids such as heroin.
Informacije na temelju zapljena upućuju na to da se ciklopropil-fentanil možda prodavao i na nezakonitom tržištu opioida kao metoksiacetil-fentanil, heroin ili u mješavinama s drugim opioidima poput heroina.
