*Abstinence = 12+ months, reported at Wave 5.
†Those abstinent from cigarettes could be using e-cigarettes or other tobacco products.
‡The continuing cohort were W4 respondents who had been surveyed at previous PATH Study waves (W1–W3).
§The W4 continuing cohort + refreshment sample 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 products used by recent former smokers were those from the cigar family (traditional cigars, cigarillos and filtered cigars) and the smokeless family (snus pouches, loose snus, moist snuff, dip, spit and chewing tobacco).
**NRT (nicotine replacement therapy) includes nicotine patch, gum, inhaler, nasal spray, lozenge or pill.
††Pharmaceutical aid includes Chantix, varenicline, Wellbutrin, Zyban or bupropion.
