Read key findings from the 2021 National Survey on Drug Use and Health (NSDUH) on substance use, mental health, and treatment. Metrics in the report cover the civilian, noninstitutionalized US population ages 12 and older. Estimates are presented by age group and by race/ethnicity for selected measures. Unlike other NSDUH Annual National Reports, the 2021 report has no discussion of trends over time, because changes in survey methodology mean the indicators are not comparable to past NSDUH estimates.

This NSDUH report discusses trends in the prevalence of mental illness, substance use disorders, or both among adolescents and adults in the United States.

This report discusses results from a survey on the use of illicit substances, alcohol, and tobacco among people ages 12 years or older. It focuses on trends between 2012 and 2013 and from 2002 to 2013, as well as differences among population groups.
