Support for regulating smoking in private and public places by adults who currently smoke and recently quit smoking in Spain.

Introduction: While indoor smoking restrictions are common, outdoor restrictions are still rare. We explored opinions and support for regulating smoking in different indoor and outdoor environments among adults who smoke and those who recently quit smoking, in Spain.

Methods: The 2021 ITC EUREST-PLUS Spain Survey is a cross-sectional study conducted among a nationally representative sample of 1006 adults aged ≥18 years who smoked cigarettes (n=867) or had recently quit smoking (n=139). Using Poisson regression with robust variance, we estimated adjusted prevalence and prevalence ratios of favorable opinions on regulating smoking in different indoor and outdoor environments and support for regulation in unregulated outdoor environments, by sociodemographic and smoking-related characteristics.

Results: There were highly favorable opinions for regulating smoking in places with minors (>95% in primary and secondary playgrounds, and cars with pre-school children and minors) and outdoor transportation (60-80%). There were less favorable opinions for regulating smoking in outdoor terraces of bars/pubs and restaurants (15-20%). Support for further total outdoor regulations on smoking was moderate for markets/shopping centers, public building entrances and swimming pools (40-60%), and low for restaurants/bars/pubs (29.2%). Having quit smoking, having no significant others who smoke and/or believing that cigarette smoke is harmful to others, were factors positively associated with favorable opinions and support for regulating smoking.

Conclusions: The settings in Spain with the most favorable opinions for regulation among adults who smoke and have recently quit smoking are places with minors, private cars with others and outdoor areas of public transportation, while the settings with the least favorable opinions were outdoor terraces of bars, pubs, and restaurants. Support for further total outdoor smoking bans is generally moderate, but low for restaurants, bars, and pubs. Overall, these findings suggest the feasibility of extending smoke-free policies to other public and private settings to protect others from tobacco smoke exposure.
