Despite UK display ban advocates’ repeated assertions, the empirical evidence does not demonstrate that tobacco display bans have reduced smoking prevalence or consumption in the four countries where they have been instituted: Canada, Iceland, Ireland, and Thailand. In this sense, display bans appear to be - like so many other tobacco control policies - highly ineffective.
A powerful and growing body of research evidence suggests that each country that implements a new tobacco display ban risks significant economic damage and a deterioration in public health.
