Best practices for expansion of smoke-free and aerosol-free environments in Europe: Protocol for the consultation to experts

Abstract

Smoke-free legislation has been shown to positively impact reducing secondhand smoke (SHS) exposure, especially in countries that have implemented comprehensive legislation rather than partial bans. Also, secondhand aerosols (SHA) that come from the heating of tobacco or liquids, with or without nicotine, in electronic nicotine delivery systems (ENDS) have been proven to increase levels of harmful substances in the air. Therefore, protection against SHS and SHA exposure and expansion of smoke- and aerosol-free environments (SAFE) should be taken into account when creating or trying to expand or enforce clean air policies. This article aims to present the protocol for a consultation with experts on tobacco and nicotine control in order to identify best practices, barriers, and opportunities for the expansion of SAFE in Europe. We identified experts among policymakers, researchers, and tobacco regulators in European countries and invited them to participate in the consultation by completing an online survey designed, programmed, and pilot-tested using Survey Monkey. The responses to the questionnaire contained quantitative and qualitative information that was thematically analyzed. The experts' consultation allowed us to produce a report on barriers and opportunities for SAFE, a report and a position paper on SAFE best practices, a web-based repository of best practices, and a weight of evidence paper that assembles evidence supporting the expansion of SAFE on indoor and outdoor spaces.
