Bystanders' Exposure to Electronic Cigarette Aerosol in Confined Settings
Abstract
Objective of this study is to investigate the bystanders' exposure to e-cigarette emissions in controlled conditions in confined settings.
Design: a cross-sectional experimental study developed in two settings: a car and a room. The experimental study will be replicated 5 times in each setting.
Three volunteers will be enrolled: 2 non-users of e-cigarettes (and non-smokers of any tobacco or nicotine product) and 1 exclusive e-cigarette user (not using any other tobacco or nicotine product) to create aerosol.
In brief, during the experimental session the e-cigarette user will be asked to use electronic cigarette during 30 minutes and two non-smokers will sit next to the user.
Individual exposure will be measured through saliva sample collection and irritation symptoms questionnaire to be collected 4 times: before exposure, just after 30 minutes of exposure, 30 minutes after the end of exposure and 3 hours after the end of exposure. Moreover, environmental exposure will be measured prior (5 min), during (30 min) and after (5 min) the exposure; particulate matter and airborne nicotine concentrations will be measure for this purpose.
Conditions: Secondhand Exposure to Electronic Cigarette.
Primary outcome: Change in airborne nicotine concentration (mg/m3).
Enrollment: 2 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 2 participants or records.
