The U.S. Department of Health and Human Services (HHS) Substance Abuse and Mental Health Services Administration (SAMHSA) released the results of its annual National Survey on Drug Use and Health (NSDUH), which shows how people living in America reported about their experience with mental health conditions, substance use, and pursuit of treatment in 2021. The 2021 NSDUH national report includes selected estimates by race, ethnicity, and age group. It is the most comprehensive report on substance use and mental health indicators that SAMHSA has released to date.
Key findings from the 2021 report include:
- Nearly two in five young adults ages 18-25 used illicit drugs in the past year.
- 9.2 million people 12 and older misused opioids.
