This study is a non-interventional observational study designed to assess the impact of passive exposure to IQOS environmental tobacco aerosol in Non-Smokers in a real-life restaurant setting.
The purpose of the study is to show that Non-Smokers, exposed to environmental tobacco aerosol from IQOS in a restaurant setting, do not have higher urinary levels of Biomarkers of Exposure (BoExp) to selected Harmful and Potentially Harmful Constituents (HPHCs), representative of Environmental Tobacco Smoke (ETS), compared to the urinary levels of BoExp measured in Non-Smokers before IQOS environmental tobacco aerosol exposure. Furthermore, the impact of passive exposure to IQOS environmental tobacco aerosol on IQOS Users and Cigarette Smokers, not using any tobacco or nicotine-containing products, will be investigated. This will enable the assessment of individuals with varying levels of exposure to HPHCs and determine whether there is any measurable additional exposure related to the environmental tobacco aerosol from IQOS. The study will also evaluate Indoor Air Quality (IAQ) through the assessment of concentrations of nicotine and selected HPHCs representative of tobacco-specific and IAQ markers in the air during exposure and non-exposure periods in a real-life restaurant setting.
Study Type
OBSERVATIONAL
Enrollment
401
Non-Exposure event of 4h duration for the individual participants, where no use of any tobacco or nicotine-containing product is allowed, designed to establish background measurements in the absence of exposure to IQOS.
Exposure Event designed to measure urinary BoExp to selected HPHCs representative of ETS in all participant groups, with up to 5h of exposure to IQOS tobacco environmental aerosol for non-smokers, cigarette smokers (not using any tobacco or nicotine-containing product, including cigarettes), and IQOS passive users (not using IQOS). Additionally, this event includes up to 8h of exposure for IQOS active users (using IQOS).
