Effects of traditional cigarette and e-cigarette tax rates on smoking and vaping outcomes among adults using a two-way fixed effects model among men: Combined BRFSS and NHIS data, 2011–2018

Outcome:	Current traditional cigarette use	Daily traditional cigarette use	Current e-cigarette use	Daily e-cigarette use	Current dual use	Current any use

Notes: BRFSS = Behavioral Risk Factor Surveillance System. NHIS = National Health Interview Survey. Each column presents partial results from a single regression model. The unit of observation is an individual in a county in a year. Data are weighted to make the number of observations for each state, year, gender, race/ethnicity, and five-year age band cohort be proportionate to its national population share. Models are estimated with a linear probability model and control for locality-level and individual-level variables reported in Table 1, county fixed effects, and quarter-by-year fixed effects. 95% confidence intervals account for within-state correlations and are reported in square brackets.

^***= statistically different from zero at the 1% level

^**= statistically different from zero at the 5% level
