The Treatment Episode Data Set - Admissions (TEDS-A) concatenated 2000-2016 and 2016 public-use files are available on the SAMHDA site. In addition, the Treatment Episode Data Set – Discharges (TEDS-D) 2015 and 2016 public-use files are also available. TEDS is a national data system of annual admissions to and discharges from substance abuse treatment facilities.


The National Survey on Drug Use and Health (NSDUH) concatenated 2002-2016 public-use file is available on the SAMHDA site. NSDUH is the primary source of statistical information on the use of tobacco, alcohol, prescription drugs, and illicit drugs by the U.S. civilian, noninstitutionalized population aged 12 or older. The survey also includes several series of questions that focus on mental health issues.


The Substate Small Area Estimates interactive visualization is live (https://pdas.samhsa.gov/saes/substate) and is linked from the State Estimates page (https://pdas.samhsa.gov/saes/state).


Users have the choice to include or exclude non-response codes using the RDAS system and send this information to the R statistical calculation server.

Previously, SAMHSA treated all missing, logically assigned, and non-response categories as missing, excluding these categories from the result set. Now, categories explicitly labeled as missing (e.g., "." in the NSDUH datasets) are excluded from the crosstab, and all other categories are included in the crosstab.
