2014 National Survey on Drug Use and Health (NSDUH) Releases

Find reports and detailed tables that present findings and data based on results of the 2014 National Survey on Drug Use and Health (NSDUH).

First Release Reports

These reports are part of the “First Release Reports” series for the 2014 NSDUH, an annual survey of the population of the United States age 12 years or older. The main First Release Report contains a cross-section of NSDUH data: substance use and substance use disorders, mental health issues among adults and adolescents, and co-occurring disorders. The three other reports focus on specific topics, such as suicide prevention, receipt of treatment, and risk and protective factors.

Behavioral Health Trends in the United States

The 2014 Behavioral Health Trends report (also available in PDF | 3.4 MB) summarizes the following:

  • Use of illicit drugs (for example, marijuana, cocaine, heroin, hallucinogens, inhalants, and the nonmedical use of prescription pain relievers, tranquilizers, stimulants, and sedatives)
  • Use of alcohol and tobacco products
  • Rates and the number of substance use disorders
  • Rates and the number of any mental illness, serious mental illness, and major depressive episode

Substance use trends also are presented for 2002 to 2014, while trends for most mental health issues are reported for 2008 to 2014.

Suicidal Thoughts and Behavior Among Adults

The 2014 Suicidal Thoughts and Behavior Among Adults report presents findings on the percentages and numbers of adults ages 18 years and older in the United States who had serious thoughts of suicide, made a suicide plan, and attempted suicide in the past 12 months. Trend data for suicidal thoughts and behavior also are presented by comparing estimates in 2014 with estimates in 2008 to 2013.

Receipt of Services for Behavioral Health Problems

The 2014 Receipt of Services for Behavioral Health Problems report (also available in PDF | 2.9 MB) presents data on substance use treatment and mental health service use among people age 12 or older. The 2014 NSDUH data is compared to estimates in 2002 to 2013 (or in 2008 to 2013 for some estimates of mental health service use).

Risk and Protective Factors and Initiation of Substance Use

The 2014 Risk and Protective Factors and Initiation of Substance Use report presents data on respondents age 12 and older regarding their perceptions of great risk of harm associated with the use of cigarettes, alcohol, and specific illicit drugs and the perceived availability of substances. The report also includes measures that are specific to youth ages 12 to 17, such as perceptions about parents strongly disapproving of youth substance use. Finally, this report includes the estimated numbers of individuals who initiated substance use in the past year and the average age at first use among people who initiated use in the past year.

Detailed Tables

The 2014 NSDUH report contains a collection of detailed tables that present data on substance use and mental health. The substance use detailed tables present national estimates of rates of use, numbers of users, and other measures related to illicit drugs, alcohol, and tobacco products, with a focus on trends between 2013 and 2014 and from 2002 to 2014, as well as differences across population subgroups in 2014. The mental health detailed tables (also available in PDF | 7.4 MB) present information on past year mental health measures and past year mental health service utilization for youths ages 12 to 17 and adults age 18 or older.

The tables present data on adults age 18 or older and include measures on the following:

  • Any mental illness
  • Serious mental illness
  • Moderate mental illness
  • Low (mild) mental illness
  • Mental health service utilization (treatment or counseling for mental health issues)
  • Suicidal thoughts and behaviors
  • Major depressive episode
  • Treatment for depression (among adults with major depressive episode)
  • Serious psychological distress

Tables with data on youths include measures on the following:

  • Mental health service utilization
  • Major depressive episode
  • Treatment for depression (among youths with major depressive episode)

Measures related to the co-occurrence of mental disorders with substance use or with substance use disorders also are presented for both adults and youths. These detailed tables focus mainly on trends between 2013 and 2014 and differences across population subgroups in 2014.

Methodology

2014 and 2015 Redesign Changes

The 2014 and 2015 Redesign Changes report describes changes in the 2014 and 2015 NSDUHs that were designed to increase the efficiency of data collection and processing and to improve the quality of the data collected. In 2014, changes were made in the sample sizes allocated to each state and to different age groups in order to increase the precision of national and many state estimates as well as estimates for older adults. In 2015, changes were made to the survey questionnaire to improve the quality of the data collected, expand the number of prescription drugs covered, and address changing substance use and mental health policy and research needs. The report provides information on the key changes made as well as some of the potential implications for data users.

Methodological Summary and Definitions

The 2014 Methodological Summary and Definitions report (also available in PDF | 582 KB) summarizes the 2014 NSDUH methods and other supporting information that are relevant to estimates of substance use and mental health issues. This report is organized into six sections:

  • Section A describes the survey, including information about the sample design, data collection procedures, and key aspects of data processing (for example, development of analysis weights).
  • Section B presents technical details on the statistical methods and measurement, such as suppression criteria for unreliable estimates, statistical testing procedures, and issues for selected substance use and mental health measures.
  • Section C contains a glossary that covers key definitions used in NSDUH reports and tables.
  • Section D describes other sources of data on substance use and mental health issues, including data sources for populations outside the NSDUH target population.
  • Section E contains a list of references cited in the report.
  • Section F lists contributors to the report.
