What? Why would you think that?
Fentanyl is 50 to 100 times more powerful than morphine, while heroin is only about twice as powerful as morphine.
Why would anyone have any use for fentanyl if it were weaker than the opiates that have already been around for over 100 years? Doesn’t make any sense.
Heroin ins a schedule 1 narcotic with potency so high as tk have jim medicinal value. There is a reason why one cannot prescribe heroin despite being a pure pain killer.
Fentanyl is a schedule 2 medication and In the IV form has a very short half life. It’s analogues carfenta and sufenta are far more potent than fentanyl itself. It is these analogies that are far more dangerous and deadly.
