Introduction:
Exposure to anti-smoking advertising and its effects differ across countries. This study examines: 1) reported exposure to anti-smoking advertising on traditional mass media and internet/social media; 2) the relationship between exposure to anti-smoking advertising and two other variables: knowledge of the harms of smoking/SHS and quit attempts in six European countries.

Methods:
Data come from the first wave of the International Tobacco Control Policy Evaluation Project 6 European Country Survey (ITC 6E) (Germany [DE], Greece [GR], Hungary [HU], Poland [PL], Romania [RO] and Spain [ES]) carried out between June 2016 and September 2016 (n=5805). Key measures included whether in the last six months participants had noticed anti-smoking advertising, their knowledge of 13 adverse smoking/SHS health effects and if they have made at least one quit attempt in the last 12 months.

Results:
RO and PL participants had significant higher odds of reporting exposure to anti-smoking advertising than DE, GR, HU and ES participants in 4 of the 6 of the media venues. Reported exposure to anti-smoking advertising was not associated with higher health knowledge in the six countries. There was a significant and positive association between exposure to anti-smoking advertising and quit attempts in the last 12 months.

Conclusions:
Participants in countries where an anti-smoking advertising campaign happened in the last 2 years, had the highest odds to report exposure to anti-smoking advertising. Participants exposed to anti-smoking advertising were more likely to make a quit attempt than those not exposed. However, exposure to anti-smoking advertising was not associated with health knowledge.
