Introduction

Results from the 2007 National Survey on Drug Use and Health: Detailed Tables is a collection of tables presenting national estimates from the National Survey on Drug Use and Health (NSDUH). This web-only publication is designed to provide tables showing greater detail than those shown in the printed report of the survey.1 These tables present information on drug, alcohol, and tobacco use; drug and alcohol dependence and abuse and treatment; mental health problems and related treatment; and the co-occurrence of substance use and mental health problems. Measures of these behaviors and characteristics are presented by a variety of demographic, geographic, and other variables. The estimates in the tables include rates of the behaviors, numbers of persons engaging in these behaviors, and other measures. Although the majority of these tables are trend tables presenting estimates from the 2006 and 2007 NSDUHs, some tables include only estimates from the 2007 NSDUH if the same or comparable data are not available from 2006. Also, there are a number of tables that contain annual averages, which are generated by combining multiple years of data if there are not sufficient data within a single year to produce reliable estimates. These tables may provide annual averages combining data for 2006 and 2007, 2004 and 2005, and 2004, 2005, 2006, and 2007. Also included are a number of tables that present data from earlier surveys in the series, including several tables presenting data from 2002 to 2007 and a couple of tables within that section presenting data from 1971 to 2007. Two tables related to respondents' mental health status were produced based on a subsample of respondents aged 18 or older.2 Finally, tables were created that present estimates corresponding to the Healthy People 2010 Objectives.3

Because of survey improvements in the 2002 NSDUH, the 2002 data constitute a new baseline for tracking trends in substance use and other measures. Therefore, estimates from the 2002 through 2007 surveys should not be compared with estimates from the 2001 or earlier surveys to examine changes over time. Methodology changes throughout NSDUH's history make it difficult to assess long-term trends from tables presenting data from 1971 to 2007. However, it is instructive to compare NSDUH estimates from 1971 to 2007 by "piecing together" the data from time periods for which data are comparable. Specifically, valid trend comparisons can be made for 1971-1998, 1999-2001, and 2002-2007. With this approach, comparisons between 1998 and 1999, and between 2001 and 2002, should be made with caution because they are potentially biased due to changes in methods. Nevertheless, when these data are combined in a single presentation, it often becomes clear that the effects of the methods changes are small compared with the major shifts in substance use prevalence that have occurred over the past three and a half decades.

The 2007 Detailed Tables include revised estimates of the nonmedical use of prescription psychotherapeutic drugs and prescription stimulants that take account data on methamphetamine use based on information obtained from survey items added to NSDUH in 2005, 2006, and 2007. In a methodological study, these measures were found to be noticeably higher when the data from the additional methamphetamine use items were taken into account. Estimates for use of illicit drugs overall and use of illicit drugs other than marijuana, however, were affected only minimally by these methamphetamine use items and were not revised. The 2006 estimates for nonmedical use of stimulants and prescription psychotherapeutics in this report have been revised based on the additional questions on methamphetamine use, and statistical adjustments have been applied to the estimates from 2002 to 2005. These modifications control for the potentially confounding effects of the questionnaire changes and enable year-to-year comparisons to be made over the period from 2002 to 2007. Section B.4.6 in Appendix B of the Results from the 2007 National Survey on Drug Use and Health: National Findings provides a discussion of the revised measures and the procedures used to generate estimates based on them.4 Because of these changes, estimates for nonmedical use of stimulant and psychotherapeutic drugs in these tables are not comparable with corresponding estimates in previous NSDUH tables and reports, and methamphetamine use estimates are not comparable with those in NSDUH tables and reports for survey years prior to 2006. Throughout these tables, notes have been added to the applicable tables to clearly document estimates that were revised.

Subsets of the Detailed Tables are included in Appendices F and G of the report titled Results from the 2007 National Survey on Drug Use and Health: National Findings. A description of the survey measurement issues and the sample design and estimation procedures used in the 2007 NSDUH can be found in technical appendices of this same report.

Table Numbering

The Detailed Tables are numbered using a three-part numbering scheme (e.g., 1.15A). The first part of the table number (1.15A) is the subject matter section to which a particular table belongs. The second part (1.15A) is the number of the table within a particular section. The third part (1.15A) is a table type indicator, an alphabetic letter appended to the table number. Each table number, as explained below, has multiple table types. Tables are numbered sequentially within each subject matter section. To the extent possible, identical tables are assigned the same table number each year except in the case where specific tables are removed or added.

The nine subject matter sections and the number of tables per section are as follows:

Section 1: Illicit Drug Use Tables - 1.1 to 1.92
Section 2: Tobacco Product and Alcohol Use Tables - 2.1 to 2.84
Section 3: Risk and Protective Factor Tables - 3.1 to 3.24
Section 4: Incidence Tables - 4.1 to 4.16
Section 5: Dependence, Abuse, and Treatment Tables - 5.1 to 5.56
Section 6: Mental Health Tables - 6.1 to 6.41
Section 7: Miscellaneous Tables - 7.1 to 7.115
Section 8: Trend Tables - 8.1 to 8.42
Section 9: Sample Size and Population Tables - 9.1 to 9.13

Table Type Purpose of the Table
A: Presents estimates of the numbers of persons exhibiting the specified behavior or characteristic (e.g., substance use) in the populations described by the column and row headings.
B: Presents estimates of the percentages of persons exhibiting the specified behavior or characteristic (e.g., substance use) in the populations described by the column and row headings.
C: Presents the standard error associated with each of the estimates in the "A" tables.
D: Presents the standard error associated with each of the estimates in the "B" tables.
N: Presents the number of cases in the specified NSDUH sample with the characteristics defined by the column and row headings.
P: Presents the p values from tests of the statistical significance of differences between columns in the "B" tables.

The majority of tables within the Detailed Tables contain five table types (A, B, C, D, and P) as defined above. Note that table type N is used exclusively within Section 9 to display the sample size counts. Exceptions to this organization are noted as follows:

Locating and Accessing a Table

The Detailed Tables are organized by table type into two categories:

Both categories are organized based on nine subject matter sections as listed below. Clicking on the subject matter section of interest will take you to an index of tables for that section. Scroll through the list of table titles to find the table of interest, and click on the table title to go directly to that table. You need to return to the Table of Contents to access tables from other sections or categories.

The nine subject matter sections are as follows:

Section 1: Illicit Drug Use Tables
Section 2: Tobacco Product and Alcohol Use Tables
Section 3: Risk and Protective Factor Tables
Section 4: Incidence Tables
Section 5: Dependence, Abuse, and Treatment Tables
Section 6: Mental Health Tables
Section 7: Miscellaneous Tables
Section 8: Trend Tables
Section 9: Sample Size and Population Tables
