The Drug Overdose Epidemic: Behind the Numbers
More than 932,000 people have died since 1999 from a drug overdose.1 Nearly 75% of drug overdose deaths in 2020 involved an opioid.2 Opioids are substances that work in the nervous system of the body or in specific receptors in the brain to reduce the intensity of pain.
Overdose deaths involving opioids, including prescription opioids, heroin, and synthetic opioids (like fentanyl), have increased by more than eight times since 1999.1 Overdoses involving opioids killed nearly 69,000 people in 2020, and over 82% of those deaths involved synthetic opioids.2
