A new peer-reviewed study published within the prestigious journal Nicotine & Tobacco Research shows that exhaled e-vapour product particles are actually liquid droplets that evaporate within seconds. “No accumulation of particles was registered within the room following subjects’ vaping. This shows us how fundamentally different exhaled e-vapour particles are compared to those released when smoking conventional cigarettes, the latter of which linger in the air for longer periods of time,” said Dr Grant O’Connell, Corporate Affairs Manager at Fontem Ventures, and senior author of the study.
The study is probably the first detailed studies conducted to research the dynamic properties of exhaled e-vapour aerosol particles. The research entitled “Characterisation of the Spatial and Temporal Dispersion Differences between Exhaled electronic cigarette mist and Cigarette Smoke,” was a collaboration between Kaunas University of Technology in Lithuania, EMPA (Swiss Federal Laboratories for Materials Science and Technology), ETH Zurich (Swiss Federal Institute of Technology) and Fontem Ventures.
During the study, Vapor E Cig used commercially available closed and open system vaping products while researchers measured particle concentrations inside the surrounding air. Unlike for conventional tobacco smoke, following immediate exhalation, scientists observed a rapid decay and evaporation of the liquid aerosol droplets, with levels returning to background levels in seconds. This was also observed under no room ventilation conditions, representing a worst case scenario.
“Exhaled e-vapour aerosol particles use a different chemical composition to tobacco smoke and here we show the physical properties will also be significantly different. This data enhances the growing body of evidence that vaping indoors is unlikely to pose an air quality issue,” said Dr O’Connell.
For e-vapour products and conventional cigarettes, the particle concentrations registered following each puff were inside the same order of magnitude. However, for e-vapour products the particle concentration returned to background values inside a matter of moments; for conventional cigarettes it increased with successive puffs, only going back to background levels after 30-45 minutes.
HE quantity of vapers are falling in America, shock new data has revealed, proving its portrayal as being a menacing new epidemic by government and anti-tobacco interest groups has become worryingly effective. About 6.9 million Americans were current users of e-cigarettes in 2017, in accordance with the latest National Health Interview Survey (NHIS), which was one million less than the previous year.
The survey, which is the source for the Centers for Disease Control and Prevention’s (CDC) national smoking estimates (the nation’s health protection agency), it can make the number of current vapers two million less than in 2014, the first year NHIS surveyed for vaping.
Data also showed the quantity of those currently using e-cigarettes who have been former smokers had increased through 2016, but dropped in 2017, from 2.62 to 2.3 million. Pro-vaping experts, who maintain e-cigarettes are key in assisting smokers make the switch away from their deadly habit, are concerned misinformation in the public domain about vaping has seen the amount of vapers tragically decline.
Long-time vaping campaigner, Clive Bates, said in the news: “American anti-vaping extremists are going to do well in fighting from the vaping threat towards the cigarette trade,” while Gregory Conley, president from the American Vaping Association, thought more needed to be done to educate smokers about the benefits of vaping and correct the misinformation they are fed.
He said after the recent data – which showed not simply a decline in vapers but an all-time drop in smokers: “We’re almost always reaching all-time low smoking prevalence. If 80% of Americans knew vaping was less hazardous rather than ~40%, we might be even lower today.”
Earlier this year, it was revealed Americans’ thought of the relative harm of e-cigarettes versus cigarettes, as measured by the National Cancer Institute’s Health Information National Trends Survey (HINTS), had risen, with more than half believing vaping was just as harmful as cigarettes.
Looking at the numbers from 2013 to 2017 (available here), Bates said: “So what difference did 4 years of better products, academic studies, journal articles and commentaries, conferences and publicly funded risk communication make? Yes, it slklbb a deterioration within these already very bad numbers…those incorrectly believing e-cigs were just like harmful or worse than cigarettes had risen from 39.8% to 55.4%.” The data comes in the identical week the American Cancer Society (ACS) admitted the American public has been misinformed about the risks of vaping – and it is now planning to market it as an alternative to smoking.
