Switch or discontinue cigar use, but continue other tobacco use W1 exclusive user who switches to another tobacco product by W3 or W1 polytobacco user that discontinues cigar use by W3 but uses another tobacco product (without discontinuing all tobacco use at W2)	20.0	(10.9 to 33.9)	32.8	(26.0 to 40.4)	27.5†	(15.6 to 43.7)	13.0^a	(9.4 to 17.8)	43.5^a,c	(40.5 to 46.6)	22.6^c	(16.5 to 30.2)	3.8^a,b	(2.3 to 6.2)	47.0^a,c	(44.2 to 49.7)	28.8^b,c	(20.7 to 38.5)

Discontinue all tobacco use W1 users who discontinue all tobacco use at either W2 and W3 or just W3	35.5	(23.1 to 50.3)	20.3	(14.4 to 27.9)	24.0†	(13.2 to 39.7)	45.3^a,b	(38.8 to 51.8)	12.0^a,c	(9.8 to 14.5)	28.5^b,c	(22.3 to 35.8)	40.7^a,b	(35.7 to 46.0)	6.3^a,c	(5.0 to 7.8)	27.5^b,c	(19.7 to 36.9)

Analysis included youth (ages 12–17), young adult (ages 18–24) and adult 25+ (ages 25 and older) W1 P30D cigar users with data at all three waves. Respondent age was calculated based on age at W1. W3 longitudinal (all-waves) weights were used to calculate estimates. All tobacco use is defined as P30D use. Use type refers to exclusive use, PTU w/CIGS or PTU w/o CIGS.
^adenotes Significant difference at p<0.0167 (Bonferroni corrected for three comparisons) between W1 exclusive cigar use and W1 cigar PTU w/CIGS.
^bdenotes Significant difference at p<0.0167 (Bonferroni corrected for three comparisons) between W1 exculsive cigar use and W1 cigar PTU w/oCIGS.
^cdeontes Significant difference at p<0.0167 (Bonferroni corrected for three comparisons) between W1 cigar PTU w/CIGS and W1 cigar PTU w/o CIGS.
The logit transformation method was used to calculate the 95% CIs.
Analyses were run on the W1, W2 and W3 Public Use Files (https://doi.org/10.3886/ICPSR36498.v8).
†Estimate should be interpreted with caution because it has low statistical precision. It is based on a denominator sample size of less than 50, or the coefficient of variation of the estimate or its complement is larger than 30%.
