Summary
Benzylfentanyl is a precursor used in the synthesis of fentanyl, not a recreational opioid. It is essentially inactive at the μ-opioid receptor. The DEA removed it from Schedule I in 2010 after concluding it has no significant opioid activity of its own; it remains a List I chemical because of its role in manufacture. There are no established human psychoactive effects. Material sold under this name is far more likely to contain fentanyl itself, or a mixture, than benzylfentanyl.
