Fentanyl is a powerful synthetic opioid analgesic that is similar to morphine but is 50 to 100 times more potent. It is used to treat severe pain, such as that caused by cancer or surgery. Fentanyl is also used as a recreational drug, and it is often mixed with other drugs, such as heroin or cocaine, to increase its effects.
Fentanyl is a very dangerous drug, and it can lead to overdose and death. In 2017, there were over 28,000 overdose deaths involving fentanyl in the United States. Fentanyl is also a major contributor to the opioid crisis in the United States.
