Dr. Paul Grin answered

Specializes in Pain Management

It is possible: Both drugs in the same class (opioids) so they will both show up the same. Fentanyl is a synthetic opioid and much stronger than morphine. When testing for Morphine, it will show positive for morphine metabolites or fentanyl. Take care.
