PATH Study Data Access

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 Available

The NIH’s National Institute on Drug Abuse (NIDA) and the FDA’s Center for Tobacco Products (CTP) announce the release of Special Collection Public-Use data files (SCPUFs) from Wave 5.5 and from the Population Assessment of Tobacco and Health (PATH) Study Adult Telephone Survey (ATS). The Wave 5.5 Special Collection data were collected from youth participants ages 13 to 19 between July and December 2020. Data in the PATH-ATS were collected between September and December 2020 from a subsample of adult participants ages 20 and older, complementing the Wave 5.5 Special Collection. Researchers may access the SCPUF at

In addition, the PATH Study Public-Use Files (PUF) have been updated to include Wave 5 Ever/Never Reference Data for all participants, which can be accessed at The Restricted-Use and Public-Use Master Linkage Files have each been updated to reflect the new SCPUF files and the current availability of biospecimens in the Biospecimen Access Program. Master Linkage Files can be accessed at

Access data and documentation for Public-Use Files at Qualified researchers from the research community can apply for access to the Restricted-Use Files through and the Biomarker Restricted-Use Files through In addition, the Biospecimen Access Program webpage provides information on how to access the urine, serum, plasma, and genomic DNA (gDNA) 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), and Wave 5 (2018-2019).

The PATH Study is a household-based, nationally representative, longitudinal cohort study of youth (12-17 years old) and adults in the United States. The study was launched in 2011 to inform FDA’s regulatory activities under the Family Smoking Prevention and Tobacco Control Act.
