Fentanyl is a powerful synthetic opioid that comes in several forms’ prescription patches and lozenges for severe pain, as well as illicit powder and pill forms made in underground labs. Because it’s extremely potent, fentanyl has a much higher risk of overdose than many other drugs.
Fentanyl can be swallowed, injected, snorted, or absorbed through the skin with patches. Illicit versions are often mixed into heroin, cocaine, or counterfeit pills, making unintentional exposure common and dangerous.
Some slang names for fentanyl include:
- China white
- Apache
- Dance fever
- TNT
- Friend
(Street names vary by region and substance form.)
