About the PATH Study

The Population Assessment of Tobacco and Health (PATH) Study is a collaboration between the National Institute on Drug Abuse (NIDA), National Institutes of Health (NIH), and the Center for Tobacco Products (CTP), Food and Drug Administration (FDA). It was launched in 2011 to inform FDA’s regulatory activities under the Family Smoking and Prevention and Tobacco Control Act. The PATH Study is an ongoing longitudinal cohort study on tobacco use behavior, attitudes and beliefs, and tobacco-related health outcomes. Data collection is planned through 2024.

Goals:

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 informing FDA’s regulatory activities related to tobacco. Specifically, the study aims to:

  • Examine susceptibility to tobacco product use;
  • Study the progression of tobacco product use, including initiation, dependence, cessation and relapse;
  • Evaluate patters of tobacco use, including:
  • Use of newer products, such as e-cigarettes or ENDS (electronic nicotine delivery systems);
  • Poly-use
  • Switching products;
  • Track potential behavioral and health impacts, including biomarkers of exposure and potential harm; and
  • Assess differences in tobacco-related attitudes, behaviors, and health conditions among racial/ethnic, gender, and age subgroups over time.

Findings

About 46,000 people aged 12 years and older, including people who did and did not use tobacco, were included in the first wave of the PATH Study. At the fourth wave in 2017, about 9,800 more participants joined the study.

Initial data on adult and youth tobacco use, published January 2017 in the New England Journal of Medicine, showed that more than 25 percent of American adults were currently using tobacco in 2013-14 and roughly 9 percent of youth reported using tobacco in the past 30 days. Multiple product use was common among people who used tobacco, accounting for roughly 40 percent of adult and youth who used tobacco, with cigarettes and e-cigarettes being the most common combination among both age groups.
