Fentanyl is a powerful synthetic opioid, basically a painkiller. It's primarily used in medicine to relieve severe pain during or after surgery. People should not consume without a doctor's prescription. Fentanyl's high potency has also made it a common adulterant in illicit drugs, especially heroin. Before taking this prescription drug, one must look for a professional or fentanyl addiction treatment center to get more knowledge about Fentanyl, its abuse, and how to treat its addiction with low side effects.​
