The document summarizes evidence from scientific studies that showed the partial smoking ban implemented in Spain in 2006 was ineffective at reducing secondhand smoke exposure. Three studies were highlighted: 1) A study found nicotine levels remained high in bars where smoking was allowed and in non-smoking areas of bars with separate rooms. 2) A study of hospitality workers found high cotinine levels and respiratory symptoms even after the law. 3) A study found PM2.5 levels far exceeded air quality standards in bars where smoking was allowed. The evidence supported a conclusion that a complete smoking ban was needed to protect workers and patrons from secondhand smoke exposure.

22. Conclusions
Different scientific studies showed, consistently, that most
hospitality workers (and costumers) were still exposed to
SHS after the law.
The evidence supported a complete ban on smoking in
hospitality sector.
The work of the scientific community has been essential
in providing evidence and objective data that contributed
to the modification of the 2006 law.
We are not very clever people doing very complicated things, just people worried for the health population trying to provide evidence, to get objective data by using reliable methods People whose work is to provide evidence of what kind of interventions Looking at the population and try to provide evidence of what kind of interventions could improve their quality of life Interventions include public health policies like the tobacco control law
