The purpose of this thesis dissertation is to define and describe the prevalence of ENDS use in smoke-free places, and assess the emission of nicotine and particulate matter from a variety of ENDS devices used by human subjects and by instrumentation in order to assess the emissions profiles of ENDS devices under ambient indoor air conditions. In Study 1, a cross-sectional assessment of Wave 2 of the Population Assessment on Tobacco and Health found that ENDS use by cigarette/ENDS co-users in smoke-free places was determined to be potentially driven in part by pro-cessation and harm reductive beliefs, such as the belief that ENDS may pose less risk to users and non-users than conventional tobacco cigarettes. This association combined with prevalence data to suggest that a majority of ENDS/tobacco co-users report using ENDS in smoke-free places, and that these users are more likely to hold a belief that these devices are safer than traditional tobacco cigarettes. Emissions assessments in Studies 2 and 3 detected that, although all ENDS emissions were observed to be significantly lower than tobacco cigarette reference groups, all ENDS devices (regardless of brand, flavor, or device design) were observed to emit significantly greater quantities of airborne PM2.5 and nicotine than were present in the exposure chamber under ambient conditions. As the health effects of exposure to chemicals emitted from ENDS devices are currently unknown, and likely to remain so until adequate longitudinal ENDS use and health data may be aggregated in the upcoming decades, the significant emission of nicotine and PM2.5 matter into indoor spaces by ENDS devices suggests that these devices should be incorporated into smoke-free indoor air laws in order to minimize potential exposure to nearby non-users.","**To request an accessible version of the file(s) associated with this item, contact library@buffalo.edu.
