The National Panel of Tobacco Consumer Studies (TCS Panel) is a probability-based panel of about 4,000 U.S. adult cigarette, cigar, and smokeless tobacco users developed by the U.S. Food and Drug Administration's Center for Tobacco Products to conduct observational and experimental studies to inform tobacco regulatory activities. This paper describes the methods and characteristics of the current panel. The TCS Panel employed a stratified 4stage sample design and in-person screening of U.S. sampled households. Selected eligible adults participated in an enrollment interview and completed a baseline survey assessing tobacco use behaviors to enroll in the Panel; 3,893 individuals were enrolled from September 2016-August 2017. Replenishment occurred from July 2019-December 2019 with 2,260 new members, for a current panel of 3,929 members. Demographic and tobacco use characteristics of the current panel were analyzed in 2020. Most demographic characteristics of the TCS Panel are similar to those of U.S. tobacco users in the 2018 National Health Interview Survey, suggesting a lack of systematic bias in the Panel. Small, but statistically significant, differences were observed in the proportion of 18- to 25-year-olds; high school diploma and bachelor's degree/higher; never married and married (p < 0.05 for all). The TCS Panel appears to be representative of U.S. cigarette, cigar, and smokeless tobacco users; such panels can be a feasible method for conducting tobacco regulatory science research. The TCS Panel has been used to field studies examining purchasing behaviors, receipt and use of free samples/coupons, and the impact of a hypothetical tobacco product standard.
