Opioid epidemic in the United States
In the United States, many painkillers that are prescribed use opioids. Opioids are effective at suppressing pain, but they can cause addiction. When people take opioids for a longer period of time, they will get addicted.  Because of this, many people in the U.S. are addicted, and there are also many addiction-related deaths. This is known as the opioid crisis or opioid epidemic
