HHS.gov: Opioids are natural or synthetic chemicals that bind to receptors in your brain or body. Common opioids include heroin and prescription drugs such as oxycodone, hydrocodone, and fentanyl.
The United States is in the midst of a prescription opioid overdose epidemic. In 2014, more than 28,000 people died from opioid overdose, and at least half of those deaths involved a prescription opioid. Many more became addicted to prescription and illegal opioids. Heroin-related deaths have also increased sharply, more than tripling since 2010. In 2014, more than 10,500 people died from heroin.
Opioid abuse is a serious public health issue, but preventive actions, treatment for addiction, and proper response to overdoses can help.
