Supplementary analyses with the full sample that included past-year alcohol abstainers were conducted and the overall pattern and significance of effects were virtually unchanged, indicating that excluding past-year abstainers did not affect our results. Further, we ran analyses to test whether the magnitude of changes in cigarette tax was related to changes in alcohol consumption. Absolute magnitude of increases in cigarette taxes were in the direction expected (greater increases in tax were associated with less heavy and less frequent drinking), however, the pattern of results was unchanged.
