Fentanyl is an extremely powerful synthetic opioid painkiller, up to 100 times more powerful than morphine, and can easily be fatal except when administered by a doctor or via prescription.
Prescription fentanyl is manufactured in extremely precise doses and its use is carefully monitored. Illicit fentanyl, on the street, is an unknown, even to the person mixing it. It is a case of trial and error – and the errors are very often fatal.
Prescription fentanyl is a powerful medical opioid prescribed in carefully monitored dosage for extreme pain and end-of-life care.
