Reference tools are provided to help users navigate the 2019 National Survey on Drug Use and Health (NSDUH) detailed tables and to define the topics presented in the tables. These tools can be used independently or in conjunction with one another for table navigation. The tools provided with the detailed tables are described in Table 1. As shown in Table 1, selected tools include hyperlinks that lead directly to the detailed tables for easy reference. This document summarizes the organization of the detailed tables and provides information on the measures and terms used in them, followed by table navigation examples.

The detailed tables are organized by table type:
The table types are grouped into two categories:
Both categories of tables include 12 subject matter sections:
Please refer to the Table Presentation section of the Introduction for more details about the table types, including some exceptions to the primary table types.
A glossary and key to selected variables are included with the detailed tables to provide more information about the measures and terms used in the tables. The glossary (Appendix A) can be used to determine how commonly used measures and terms are defined in the 2019 detailed tables and what other related selected topics are available. Where relevant, cross-references to additional details in the 2019 NSDUH methodological summary and definitions report are provided.1 The glossary may also be helpful when used in conjunction with the table of contents (TOC), the list of tables (LOT), and the new search feature in identifying tables that contain information for selected topics. The key to selected variables can be used to determine the categories that are displayed in the tables for a respective measure or term. The key to selected variables is designed to be used in conjunction with the TOC but may be helpful when using other reference tools as well.
For example, a user who has identified tables of interest (e.g., Tables 1.22 to 1.63), and would like more information about a topic included in those tables (e.g., race), can look up that topic (e.g., race) or the categories displayed for that topic (e.g., "NHOPI," "Two or More Races," "Hispanic or Latino") in the glossary (Appendix A) to obtain more information. Alternatively, a user interested in tables that present information about the prevalence of alcohol use measures can first review the "Alcohol Use" entry in the glossary. By looking up "Alcohol Use" in the glossary, a user will find information about how alcohol use is defined, the alcohol use questions, and related measures (i.e., "Binge Use of Alcohol," "Current Use or Misuse," "Heavy Use of Alcohol," "Lifetime Use or Misuse," "Past Month Use or Misuse," "Past Year Use or Misuse," "Recency of Use or Misuse," and "Underage Alcohol Use"). The related measures provide the time periods shown for the "Alcohol Use" measure, as well as other types of alcohol use measures. After reviewing the definitions for the various available measures, the user can determine measures of interest and use the TOC, LOT, or search feature to identify tables that contain the selected measures.
The TOC can be used to identify groups of tables in each of the 12 subject matter sections in the 2019 detailed tables. A user can click on the HTML or PDF links and be taken directly to the first table in the specified group or the first table in a corresponding group of multiyear or 2-year tables, if applicable. In addition, if the terms that define the group of tables are the first occurrence of those terms in that section of the TOC, a user can click on those terms to access the key to selected variables, which shows the categories displayed in the tables for the respective terms. If a term used to define the group of tables is not the first occurrence in that section of the TOC, the user would need to scroll up to the first occurrence in the section and click on that term to access the key to selected variables and see the categories displayed in the tables. A user can go directly to the key to selected variables by scrolling to the top of the TOC and clicking on the associated link.
For example, a user interested in information about the prevalence of illicit drug use by age can first review the TOC and see that tables pertaining to illicit drug use can be found in Section 1: Illicit Drug Use/Misuse Tables. Scanning through Section 1 of the TOC, the user can see that data on the prevalence of illicit drug use by standard age categories are provided in Tables 1.1 to 1.5. If a user would like more information concerning terms shown in these tables, then the key to selected variables is helpful. If a user clicks on the term "standard age categories" (the first occurrence of this term in Section 1 of the TOC), the link will take the user to the key to selected variables, which displays the categories 12 or Older, 12-17, 18 or Older, 18-25, and 26 or Older. However, the term "illicit drug use/misuse" is not the first occurrence of this term in Section 1 of the TOC, so this term is not linked to the corresponding term in the key to selected variables. By scrolling up in the TOC, a user can find the first occurrence of that term. Clicking on the first occurrence of the term will open the key to selected variables, displaying the "illicit drug use/misuse" categories. To access the detailed tables of interest, the user can click on "PE" under the HTML or PDF column in the TOC to open Table 1.1A, which is the first prevalence estimate table available for this table number. Clicking on "SE" under either column will open Table 1.1C, which is the first standard error and p value table available for this table number. These 2-year tables also have corresponding multiyear tables that are listed in the TOC as Tables 7.1 to 7.15. Similar to the links for the 2-year tables, the "PE" or "SE" links under the HTML or PDF column go to Table 7.1A or 7.1C, respectively.
For the 2019 detailed tables, a robust search feature has been added to help users navigate particular tables. When a keyword or short phrase is entered in the search box, the search returns a list of the tables that contain that term, including links to those tables (by table type). This search is operational from within the TOC, the combined HTML file of the detailed tables, and individual HTML tables or table sections. The search does not include the content of table notes or footnotes.
The LOT can be used to identify a specific table in the subject matter sections listed previously. For each table in a section, the LOT provides the table number, table type indicators, and a condensed version of the table title. To reduce redundancy, the portion of the actual table title that describes the table type is omitted. At the top of the LOT, the six table types are defined for easy reference. An example of a condensed table title is shown as follows.
Table 1.1 (A, B, C, D, P) Types of Illicit Drug Use in Lifetime, Past Year, and Past Month among Persons Aged 12 or Older: 2018 and 2019
A user can click on the HTML or PDF version of the LOT. For the HTML LOT, a user can then click on any of the table type indicators included in the parentheses to go to the specified part for that table number. For the PDF LOT, the table type indicators are not linked to the tables.
For example, a user interested in information about the prevalence of past month alcohol use among persons aged 12 to 20 can review the LOT in Section 2: Tobacco Product and Alcohol Use Tables and identify Table 2.32 and Table 2.34 as the tables of interest. In the HTML LOT, a user can click on the "A" in the parentheses after either of these table numbers to go to the numbers in thousands and click on the "B" to go to the percentage tables. In the PDF LOT, a user would need to move to the Section 2 PDF bookmark to locate the tables of interest or go to the TOC and click on the group of tables that includes the tables of interest.
