Introduction:
This paper aims to examine changes in the smokers’ support for bans in different settings, and explore the determinants of changes in smokers’ opinions about smoking in different settings in six European countries.

Methods:
Longitudinal survey (the ITC 6 European Country Survey, part of the EUREST-PLUS Project) using nationally representative samples of adult smokers in Germany, Greece, Hungary, Poland, Romania and Spain. Data were collected in 2016 (wave 1) and 2018 (wave 2). Generalized estimating equation logistic regression models were used to estimate the support in each wave and then test the change in adjusted percentages between waves.

Results:
In the six countries there was an overall significant increase in support for smoking bans in nine out of eleven settings. Policies that protect children and teenagers against smoke continued to be the most supported in wave 2 (>90%). Smokers in Greece were outliers in comparison to other countries with a decrease in their support in nine out of eleven policies surveyed. In contrast, smokers in Hungary and Spain had an increase in their support in all policies. Smokers belonging to the younger age group had the biggest increase in support for smoking bans. Those who quitted between waves consistently had higher support for smoking bans compared to daily smokers.

Conclusions:
The support for smoke-free regulations increased among European smokers. Specific groups of smokers should be studied to determine why they are still resistant to support smoke-free regulations and how to tailor interventions to inform them about the benefits of such regulations.
