SAMHSA’s 2018 National Survey on Drug Use and Health (NSDUH) Report Data Findings
Today, SAMHSA released the latest data findings from the 2018 NSDUH. NSDUH provides estimates of the use of illegal substances, prescription drugs, alcohol, and tobacco, as well as mental disorders, treatment, and co-occurring substance use and mental disorders in the United States. NSDUH data also help to identify the extent of substance use and mental illness among different sub-groups; estimate trends over time; and determine the need for treatment services.
View a video presentation of the NSDUH data findings by Assistant Secretary for Mental Health and Substance Use, Dr. Elinore F. McCance-Katz, MD, PhD.

Annual National Report
Key Substance Use and Mental Health Indicators in the United States
NSDUH’s latest annual report focuses on substance use and mental health in the United States based on NSDUH data from 2018 and earlier years. The annual report presents estimates that meet the criteria for statistical precision and facilitate stable examination of trends over time to study changes in society and emerging issues. The 2018 Key Substance Use and Mental Health Indicators report summarizes the following:
- Substance use (alcohol, tobacco, marijuana, cocaine, heroin, hallucinogens, and inhalants, as well as the misuse of opioids, prescription pain relievers, tranquilizers or sedatives, stimulants, and benzodiazepines)
- Initiation of substance use
- Perceived risk from substance use
- Substance use disorders
- Any mental illness, serious mental illness, and major depressive episode
- Suicidal thoughts, plans, and non-fatal attempts for adults aged 18 or older
- Substance use treatment and mental health service use
The 2018 NSDUH Detailed Tables present national estimates of substance use and mental health. The focus is on trends between 2017 and 2018 and from 2002 to 2018, as well as differences across population subgroups in 2018. These tables present information for youths aged 12 to 17 and adults aged 18 or older (separately and combined) on drug, alcohol, and tobacco use, as well as substance use disorder (SUD), risk and availability of substance use, treatment, health topics, and alcohol consumption. Please refer to Chapter 4 of the Methodological Summary and Definitions report for more information.
