    The National Survey on Drug Use and Health (NSDUH): 2-Year R-DAS study has been updated to include data for the years 2012 and 2013 and can now be used to create combined 2-year estimates for the years: 2002-2003, 2004-2005, 2006-2007, 2008-2009, 2010-2011, and 2012-2013. more...

    The 2-Year R-DAS NSDUH study is available for online analysis using the Restricted-use Data Analysis System (R-DAS).

    The 2-Year R-DAS NSDUH study includes a modification to the mapping of certain “OTHER, Specify” race responses to the detailed race categories reported in the IRNWRACE and NEWRACE1 variables. Specifically, responses of "Pakistan," "Bangladesh," "Nepal," and "Bhutan," that were previously mapped to "Asian Indian," are now mapped to "Other Asian."

  • 2013 National Survey on Drug Use and Health (NSDUH) Public-use Data File Released

    The public-use data and documentation files for the 2013 National Survey on Drug Use and Health (NSDUH) are now available for download, online analysis, and quick tables. The 2013 NSDUH report and detailed tables, presenting national estimates from the 2013 NSDUH, are also available. more...

    The 2013 NSDUH public-use data file contains new variables related to:

    • Military status. Respondents were asked about service in a Reserve component of the military and about military veteran status. Respondents who had previously been in the U.S. Armed Forces were asked three additional questions about whether they had ever been on active duty; the period in which they served in active duty; and whether they served in a military combat zone or an area where they drew imminent danger pay or hostile fire pay.

    • Marijuana usage. Respondents indicating past year marijuana use were asked whether any or all of their past year marijuana use was recommended by a doctor or other health care professional. A variable is also available to indicate whether respondents were living in a State in which a law allowing use of marijuana for medical reasons was in effect at the time of the interview.

    • Height and weight. Respondents were asked about height and weight, which was used to create a new recoded BMI variable.

    • Screening questions during health care visits. Respondents were asked about screening for tobacco, alcohol, or other drug use as part of their health care visits in the past 12 months and about discussions respondents had with health care professionals about their tobacco, alcohol, or other drug use as part of their health care visits.

    • Geography. A geographic variable identifying respondents residing in American Indian areas (AIAs) is available for the first time in the NSDUH public-use file.

    The Changes for 2013 section of the codebook contains additional information on these new variables. Updates to variables previously available in the NSDUH public-use file are also described.

    The 1979, 1982, 1985, 1988, and 1990 through 2013 NSDUH public-use data files are available on the SAMHDA website. The NSDUH is the primary source of national and state-level estimates on the prevalence, patterns, and consequences of alcohol, tobacco, and illegal drug use and abuse in the general U.S. civilian non-institutionalized population. The survey is also a source of national estimates on mental health measures such as SMI, depression, and treatment. NSDUH data are collected annually through nationally representative interviews with approximately 70,000 randomly selected individuals aged 12 and older.

    The 2013 NSDUH restricted-use data is planned for release via the R-DAS and Data Portal early next year.
