While smoking indoors is likely to harm others who inhale the second hand smoke trapped in the space, vaporizing indoors is unlikely to pose the same risk. That is according to a new study, collaborated on by the three educational institutions: the independent Kaunas University of Technology in Lithuania, EMPA Swiss Federal Laboratories for Materials Science and Technology, and ETH Zurich the Swiss Federal Institute of Technology. The resulting paper was presented at the fourth Workplace and Indoor Aerosols conference in Barcelona. The study set out to discover data about how vaporizers and e-cigarettes affect the air quality when used indoors. They asked: Does vaporizing indoors pose a risk to bystanders (non-vapers)?
Tobacco cigarettes affect the air quality when smoked in an enclosed space because the smoke particles remain in the air, building up over time instead of dissipating. This paper is the first of its kind with compelling evidence that e-cigarette particles evaporate seconds after being exhaled. A non-vaper in the same room only risks being being exposed to the aerosol particles of a closed-circuit e-cigarette for a few seconds after the person vaping exhales them. It's also the first to show the effects of vaping in a realistic situation, the research showing clearly that there is no affect to the air quality when vaping was contained indoors.
The study is a necessary one because it starts to address an issue that has be the cause of some confusion. That is, establishments not knowing whether or not vaping should be allowed indoors. The question has restaurant servers unsure of whether to confront vaping diners or leave them to vape in peace.
It is important to note here that while the study was conducted by three independent educational bodies, it was initiated by Fontem Ventures, owner of two e-cigarette brands. Dr. Grant O'Connell, Vice President of Corporate and Regulatory Affairs, Fontem Ventures had the following to say about the study, in a related press release.
"This study shows that e-cigarettes - similar to other consumer aerosol-based products - release e-liquid primary particles into the air that disappear extremely quickly. "But importantly, this also tells us how fundamentally different exhaled e-cigarette particles are compared to those emitted by smoking conventional cigarettes, the latter of which are reported to linger in the air for long periods of time. By contrast, no accumulation of particles was registered in the room following e-cigarette use."
