Changes in the prevalence of tobacco consumption and the profile of Spanish smokers after a comprehensive smoke-free policy

Background: A partial smoke-free regulation in Spain was introduced on January 1, 2006, which was subsequently amended to introduce a comprehensive smoke-free policy from 2 January 2011 onward. The objective of this study was to compare the prevalence of tobacco consumption in Spain and the profile of smokers before (2006) and after (2011) the comprehensive smoking ban passed in 2010. Methods: Two independent, cross-sectional, population-based surveys were carried out among the adult (≥ 18 years old) Spanish population in 2006 and 2011 through telephone interviews. Both surveys used the same methods and questionnaire. Nicotine dependence was assessed with the Fagerström Test for nicotine dependence and readiness to quit according to the stages of change. Results: The prevalence of tobacco consumption showed a nonsignificant decrease from 23.4% in 2006 to 20.7% in 2011. No changes were observed in nicotine dependence or readiness to quit. In 2011, most smokers (76%) showed low nicotine dependence and were mainly in the precontemplation stage (72%). Conclusions: The prevalence of smokers has slightly decreased since the introduction of the total smoking ban in Spain. No differences were found in nicotine dependence or readiness to quit.
