What ingredients are in fentynal?

Fentanyl is a synthetic opioid primarily composed of the chemical compound N-phenyl-N-[1-(2-phenylethyl)piperidin-4-yl]propanamide. It is typically produced in a laboratory setting and does not contain traditional "ingredients" like food products. Fentanyl is often mixed with other substances or adulterants for illicit use, which can include various cutting agents, but its primary active ingredient is fentanyl itself.
