Objective.
To evaluate the impact of menthol cigarette bans in seven Canadian provinces
between 2016 and 2018.
Methods.
Longitudinal data from the Canadian arm of the 2016 and 2018 ITC Four Country
Smoking and Vaping Survey. 1098 non-menthol and 138 menthol smokers were
surveyed pre-menthol and post-menthol cigarette bans. Multivariate logistic
regression models examined associations between pre-post ban changes in smoking
behaviour, including differences between menthol and non-menthol smokers in
quit attempts and quitting.
Results.
At follow-up, 59.1% of pre-ban menthol smokers switched to non-menthol
cigarettes; 21.5% quit smoking and 19.5% still smoked menthols, primarily
purchased from First Nations reserves. Menthol smokers were more likely than
non-menthol smokers to make a quit attempt (adjusted OR (aOR)=1.61, 95% CI 1.03
to 2.51), and to remain quit (aOR=2.30, 95% CI 1.06 to 5.01). Menthol smokers
did not differ significantly from non-menthol smokers in quit success
(aOR=1.72, 95% CI 0.98 to 3.01); however, daily menthol smokers were more
likely than daily non-menthol smokers to quit (aOR=2.21, 95% CI 1.15 to 4.24),
and daily menthol smokers who quit before the ban were more likely than daily
non-menthol smokers to remain quit (aOR=2.81, 95% CI 1.15 to 6.85).
Conclusions.
Although menthol smokers were most likely to switch to non-menthol cigarettes,
the menthol ban was also significantly associated with higher rates of quit
attempts and quit success among menthol smokers compared with non-menthol
smokers, and may have helped to prevent relapse among menthol smokers who had
quit smoking before the ban. Results confirm and extend evaluation of Ontario’s
menthol ban across provinces covering 83% of the Canadian population.
