Data from the Population Assessment of Tobacco and Health (PATH) Study are available for use by researchers wanting to explore their own study questions. This includes both publicly available files that can be downloaded and analyzed on any computer and restricted-access files that researchers can apply to access on a secure server. Data and documentation (questionnaires, codebooks) related to the PATH Study are available at the study website at the National Addiction & HIV Data Archive Program (NAHDAP), including instructions for access to restricted- and public-use files. Available file types include Questionnaire Public-use Files (PUFs), Questionnaire Restricted-use Files (RUFs), Biomarker Restricted-use Files (BRUFs), State Identifier Restricted-use Files (SIRUFs), Tobacco Universal Product Code (TUPCRUF) Data, Special Collection Public-use Files (SCPUFs), and Special Collection Restricted-use Files (SCRUFs). Data from new waves are released as they become available.
New PATH Study Data Files from Wave 7
NIH’s National Institute on Drug Abuse and FDA’s Center for Tobacco Products are announcing the release of the Wave 7 Public-Use File from the Population Assessment of Tobacco and Health (PATH) Study. These Wave 7 files contain questionnaire data collected between January 2022 and April 2023.
The Public-Use Files are available for download. Additionally, the Master Linkage Files have each been updated to reflect the current availability of biospecimens in the Biospecimen Access Program.
Researchers are also encouraged to apply for access to the Restricted-Use Files and Biomarker Restricted-Use Files. In addition, the Biospecimen Access Program webpage provides information on how to access the urine, serum, plasma, and genomic DNA collected from adult PATH Study participants during Wave 1 (2013 – 2014) and urine collected during Wave 2 (2014 – 2015), Wave 3 (2015-2016), Wave 4 (2016-2018),Wave 5 (2018-2019), and Wave 7 (2022-2023).
