IntroductionOver half of US adults who smoke cigars use flavored cigars, illustrating their broad appeal; however, their long-term impact on cigar and cigarette use is unknown.MethodsUsing restricted data from Waves 1-5 (2013-2019) of the Population Assessment of Tobacco and Health Study, we investigated cross-sectional patterns and longitudinal transition rates of unflavored and flavored cigar use with and without cigarettes among a nationally representative sample of US adults.ResultsProportionally, more adults who used flavored cigars without or with cigarettes were younger and female. More adults with exclusive cigar use were non-Hispanic Black. More adults with dual use had lower educational attainment. The median number of cigars smoked daily and tobacco dependence was highest among adults who used flavored cigars with cigarettes. Only 14.6% of adults with exclusive flavored cigar use at Wave 1 continued their use to Wave 5, with most transitioning to non-current (46.4%) or exclusive cigarette use (22.9%). Likewise, 13.8% of adults with dual flavored cigar and cigarette use at Wave 1 continued their use to Wave 5, with 57.6% transitioning to exclusive cigarette use and 19.7% transitioning to non-current use. Comparatively, 72.9% of adults with exclusive cigarette use continued their use to Wave 5, while 23.6% transitioned to non-current use.ConclusionAdult cigar use was less stable than cigarette use, particularly among those who use flavored cigars. Future research should investigate whether these transition patterns between flavored and unflavored cigar and cigarette use vary across sociodemographic groups and their potential long-term health implications.Copyright © 2024 The Authors.
