National Survey on Drug Use and Health (NSDUH) Data Files Updated
Updated files include revised mental illness variables that are based on a revised statistical model which predicts whether an adult NSDUH respondent had serious, moderate, mild, or no mental illness. The revised mental illness variables in the 2008 to 2011 NSDUH public-use data files are now comparable to the mental illness variables available in the 2012 NSDUH data file. For more information on the updated variables, users may refer to the "New and Corrected Data Since Last Release" section of the codebooks for each year. Additional information on the revised model is available in the technical report from SAMHSA.
In addition, the NSDUH: 2-Year R-DAS (2002-2003, 2004-2005, 2006-2007, 2008-2009, and 2010-2011) file has been updated with the revised mental illness variables. The 2-Year R-DAS file is available for analysis using the Restricted-use Data Analysis System (R-DAS). The NSDUH 2-Year R-DAS file includes a number of geographic variables that are unavailable in NSDUH public-use files.
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 serious mental illness (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 NSDUH is conducted by the Substance Abuse and Mental Health Services Administration (SAMHSA).

TEDS-D is one component of the Behavioral Health Services Information System (BHSIS), maintained by the Center for Behavioral Health Statistics and Quality (CBHSQ), SAMHSA. TEDS-D records annual discharges from substance abuse treatment facilities, primarily ones that receive public funding. Demographic information such as gender, race, ethnicity, education, and employment status, among others, are included in the data. The reason for discharge and the length of time in treatment are also included in the file. Substances reported in TEDS-D include alcohol, cocaine and crack, marijuana and hashish, heroin, nonprescription methadone, other opiates and synthetics, stimulants, tranquilizers, sedatives, and over-the-counter medications, among others.
