Other tobacco product use: any use of other e-products, cigar, cigarillo, filtered cigar, pipe, hookah, snus or smokeless tobacco.
*Recent former cigarette smoker: those who were not smoking cigarettes at Wave 4 but who were established smokers 1 year earlier.
†Re-quit is a relapse to smoking since the previous survey followed by an additional quit attempt (we classify 3+ months off as a significant re-quit attempt).
‡The continuing cohort were W4 respondents who had been surveyed at previous PATH Study waves (W1–W3).
§The total W4 population is the continuing cohort + refreshment sample and includes all people interviewed for the PATH Study in 2017 (W4). The purpose of the refreshment sample (those first interviewed at W4) was to reset the size of the cohort and reduce the weighting needed to make estimates that were nationally representative of the US population.
¶Other tobacco use includes all other tobacco products including the combusted tobacco products and smokeless products, but not e-cigarettes.
**Any cigar use includes traditional cigars, cigarillo and filtered cigars.
††Any combusted tobacco product use: any use of cigar, cigarillo, filtered cigar, pipe or hookah.
