What is fentanyl?

Fentanyl is a powerful synthetic opioid analgesic that is similar to morphine but is 50 to 100 times more potent. In its prescription form it is prescribed for pain, but fentanyl is also made illegally.
Illegal fentanyl is sold in the following forms: as a powder, dropped on blotter paper like small candies, in eye droppers or nasal sprays, or made into pills that look like real prescription opioids.
Fentanyl works by binding to the body’s opioid receptors, which are found in areas of the brain that control pain and emotions. Its effects include extreme happiness, drowsiness, nausea, confusion, constipation, sedation, tolerance, addiction, respiratory depression and arrest, unconsciousness, coma, and death.

Illegal fentanyl is being mixed with other drugs, such as cocaine, heroin, methamphetamine, and MDMA. This is especially dangerous because people are often unaware that fentanyl has been added.
The high potency of fentanyl greatly increases risk of overdose, especially if a person who uses drugs is unaware that a powder or pill contains it. They can underestimate the dose of opioids they are taking, resulting in overdose.
