What Is Carfentanil?
An elephant tranquilizer not approved for use in humans and 10,000 times more potent than morphine, carfentanil is a synthetic opioid drug. The Drug Enforcement Administration (DEA) warns that it is even 100 times more potent than the extremely powerful drug fentanyl, of which it is an analogue.
Opioid drugs target opioid receptors in the brain, filling them up. When this happens, functions of the central nervous system that are automatic, like breathing, body temperature, blood pressure, and heart rate slow down. Pain sensations are dulled, and anxiety is reduced. Dopamine, one of the brain’s chemical messengers, floods the brain, increasing pleasure. Parts of the brain that help to control a person’s impulses, govern learning and memory, and regulate moods are disrupted. In short, an opioid drug makes users feel relaxed and happy.
Carfentanil is an extreme version of other opioid drugs, more powerful and therefore potentially more dangerous. Carfentanil may be snorted, smoked, ingested, or injected. Any use of this drug in humans is abuse, as it is not regulated for human consumption.
