Introduction and objective:
Smoking-free policies protect non-smokers from the negative effects of smoking, but many young adults still use products containing nicotine. The aim of this article is to analyze the factors that influence young people’s attitudes towards the ban on smoking in public places.

Material and methods:
Data were obtained from a representative sample of young adults aged 13–15 from the Global Youth Tobacco Survey (GYTS) conducted in the Czech Republic, Lithuania, Romania, Slovakia and Slovenia. Logistic regression analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs).

Results:
At least a quarter of the adolescents were exposed to cigarette smoking, about 40% have parents who smoke and over 50% declared that they have peers who smoke. A higher proportion of adolescents have knowledge about the harmful effects of second-hand smoking (62.6–71.9%), but at least one-fifth of young people are still exposed to the marketing of tobacco products. Compared with current smoking, those with never smoked were significantly associated with positive attitude toward to restricting smoking in all five analyzed countries, with an AOR= 4.74 (95% CI: 3.61–6.23), AOR=4.33 (95% CI: 2.32–8.07), AOR=2.85 (95% CI: 2.19–3.70) and AOR=2.45 (95% CI: 1.65–3.64), respectively. Gender, age, smoking, exposure to second-hand smoke, knowledge about the harmful effects of smoking, anti-smoking education, seeing people using tobacco and exposure to tobacco marketing, were significantly associated with the attitudes of young people towards restricting smoking in public places.

Conclusions:
The study provides useful information on factors that should be taken into account when planning anti-smoking strategies so that young people are able to resist the pressure to use tobacco products.
