PATH - Population Assessment of Tobacco and Health - A collaboration between the NIH and FDA

About the PATH Study

The Population Assessment of Tobacco and Health (PATH) Study is a uniquely large, long-term study of tobacco use and health in the United States. A collaboration between the U.S. Food and Drug Administration (FDA) Center for Tobacco Products and the National Institutes of Health (NIH) National Institute on Drug Abuse (NIDA), the study was launched in 2011 and started the first wave of data collection in 2013. For updates on PATH Study data collection, see “PATH Study FAQs for Researchers.” 

By following study participants over time, the PATH Study helps scientists learn how and why people start using tobacco, quit using it, and start using it again after they’ve quit, as well as how different tobacco products affect health (such as cardiovascular and respiratory health) over time. Findings from the study may also inform FDA’s actions related to tobacco products, thereby helping to achieve the goals of the Family Smoking Prevention and Tobacco Control Act.

The PATH Study is conducted via a contract awarded to Westat and involves researchers from:

  • Centers for Disease Control and Prevention 
  • Center for Tobacco Products, FDA
  • Dartmouth College
  • National Institute on Drug Abuse, NIH
  • New York University
  • Roswell Park Cancer Institute
  • Rutgers, The State University of New Jersey
  • Truth Initiative (formerly Legacy)
  • The Medical University of South Carolina
  • The University of California, San Diego
  • The University of Minnesota
  • The University of Waterloo

By monitoring and assessing behaviors, attitudes, biomarkers, and health outcomes associated with tobacco use in the United States, the PATH Study helps enhance the evidence base available to inform FDA’s regulatory activities related to tobacco. Specifically, the study aims to:

  • Examine what makes people susceptible to using a tobacco product
  • Evaluate initiation and use patterns, including the:
    • use of newer products, such as  e-cigarettes or ENDS (electronic nicotine delivery systems)
    • use of multiple products
    • switching from one product to another
  • Study patterns of tobacco product use, cessation, and relapse
  • Track potential behavioral and health impacts, including biomarkers of exposure and harm
  • Assess differences in tobacco-related attitudes, behaviors, and health conditions among racial/ethnic, gender, and age subgroups

Researchers interested in the PATH Study are encouraged to create an account to join the PATH Study Data User Forum. The forum enables researchers using PATH Study data to submit and answer questions. Announcements, data releases and updates, new publications, upcoming events, and other information for PATH Study data users are also posted to the forum.

Questions about the collection, content, weighting, documentation, or structure of PATH Study data may be submitted to the new Westat email: [email protected].

NOTE: This email address is not for questions about statistical analysis or analytic guidance. For analytic questions, researchers may wish to consult with statisticians and analysts at their institutions. Additionally, the PATH Study User Forum can be used to obtain feedback and engage in discussion with other PATH Study data users.
