Fentanyl is a synthetic opioid, approved for treating severe pain. It is 50 to 100 times more potent than morphine. However, illegally made fentanyl is sold through illegal drug markets for its heroin-like effect. It is often mixed with other drugs —with or without the user’s knowledge—to increase its euphoric effects. For information on Fentanyl, visit the sites listed below.
