4. Fentanyl
Fentanyl is also called Fentanil, and it is a pain medication made from opioids. It can be up to 100 times more potent than morphine. If the drug is used outside of medical needs, it can be deadly and dangerous. It is often abused because of the feeling of intense pleasure that the recreational user may experience if they inject or ingest the drug. The treatment for fentanyl addiction will be important even after having used it for some time. Medical treatment with fentanyl detox will make it easier to reduce the physical effects that are caused by discontinuing the fentanyl.
