Study Shows Little Risk from “Secondhand Vapor”

Blu manufacturer Fontem Ventures funds important air quality study

A new study shows that e-cigarette vapor exhaled by the user probably poses no risk to bystanders. The study found that vapor particles consist of droplets that evaporate almost immediately after exhalation.

The study was conducted at independent Lithuanian and Swiss academic institutions and laboratories, and was presented at the Workplace and Indoor Aerosols conference in Barcelona, Spain. It was funded by Fontem Ventures, owner of blu e-cigarettes. Fontem is a subsidiary of Imperial Tobacco.

Vapor and smoke particles are different


The researchers measured particle concentrations in the air during and after use of closed-system e-cigarettes (cigalikes). They found the particles dropped to background levels within seconds of the vapor being exhaled. The results were the same in rooms with and without ventilation.

Dr. Grant O’Connell, Vice President of Corporate and Regulatory Affairs at Fontem Ventures, said, “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.”  

“This initial data supports the conclusions of Public Health England, the Chartered Institute for Environmental Health, Cancer Research UK and others that vaping indoors is unlikely to pose an air quality issue to bystanders and non-vapers,” said Marc Michelsen, Senior Vice President of Corporate Affairs and Communications at Fontem.

“This study adds to the evidence”

According to Dr. Michael Siegel, professor at Boston University School of Public Health, the results are significant.  “The important finding is that although exhaled e-cigarette aerosol does contain a high concentration of particulates, the aerosol dissipates within seconds,” Siegel, a longtime proponent of vapor products, told the Daily Caller.

“This means that the particulate matter does not accumulate,” he added, “unlike tobacco smoke, which we know lingers in the air causing the concentration to build up over time. This study adds to the evidence that vaping poses minimal risks to exposed bystanders.”

I spend most of my time studying the regulatory, legislative and scientific challenges to vaping, advocating for our right to exist, and talking with others who do the same. Consider me a source for information, and feel free to agree or disagree with anything I say. I love good coffee and sweet Michigan cherries. My childhood hero was Gordie Howe.

    This is great news. It now adds to study’s that have been done that have already proven this. It’s just a shame that this will never make it to the large news channels in the USA (Fox News, CNN CBS News etc.) and probably not any major news channel anywhere else in the world. If the news stations and our governments would acknowledge all of the testing that has been done then the people of the world who are blind to the effects of vaping may just get a little more educated and would not look down so harshly on it.

    I have to give a thanks to you Jim McDonald. You have been replying to the posts I’ve been putting up lately and I want to let you know that I appreciate your time and your opinions.

      Thanks, Tim! I appreciate all vapers that look below the surface of what’s going on, which you obviously do. And the folks who run Vaping360 strongly agree with me that it’s important to engage with our readers. After all, we’re all in this together!
