A new peer-reviewed study published within the prestigious journal Nicotine & Tobacco Studies have shown that exhaled e-vapour product particles are actually liquid droplets that evaporate within a few moments. “No accumulation of particles was registered in the room following subjects’ vaping. This shows us how fundamentally different exhaled e-vapour particles are when compared with those released when smoking conventional cigarettes, the latter of which linger within the air for longer time periods,” said Dr Grant O’Connell, Corporate Affairs Manager at Fontem Ventures, and senior author of the study.
The study is among the first detailed studies conducted to research the dynamic properties of exhaled e-vapour aerosol particles. The analysis entitled “Characterisation from the Spatial and Temporal Dispersion Differences between Exhaled e-cigarette mist and Tobacco Smoke,” was actually 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 Cigarettes used commercially available closed and open system vaping products while researchers measured particle concentrations within the surrounding air. Unlike for conventional tobacco smoke, following immediate exhalation, scientists observed a rapid decay and evaporation from the liquid aerosol droplets, with levels going back to background levels within a few moments. This is also observed under no room ventilation conditions, representing a worst case scenario.
“Exhaled e-vapour aerosol particles use a different chemical composition to cigarette 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 aura quality issue,” said Dr O’Connell.
Both for e-vapour products and conventional cigarettes, the particle concentrations registered following each puff were in the same order of magnitude. However, for e-vapour products the particle concentration returned to background values inside a couple of seconds; for conventional cigarettes it increased with successive puffs, only returning to background levels after 30-45 minutes.
HE number of vapers are falling in America, shock new data has revealed, proving its portrayal as a menacing new epidemic by government and anti-tobacco interest groups continues to be 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 had been one million fewer than the earlier year.
The survey, the source for the Centers for Disease Control and Prevention’s (CDC) national smoking estimates (the nation’s health protection agency), it will make the quantity of current vapers two million less than in 2014, the very first year NHIS surveyed for vaping.
Data also showed the amount of those currently using e-cigarettes who were 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 actually concerned misinformation inside the public domain about vaping has seen the number of vapers tragically decline.
Long-time vaping campaigner, Clive Bates, said from the news: “American anti-vaping extremists are going to do well in fighting from the vaping threat to the cigarette trade,” while Gregory Conley, president from the American Vaping Association, thought more must be completed to educate smokers about the advantages of vaping and correct the misinformation they are fed.
He stated after the recent data – which showed not just a decline in vapers but an all-time drop in smokers: “We’re more often than not reaching all-time low smoking prevalence. If 80% of Americans knew vaping was less hazardous instead of ~40%, we could be even lower today.”
Earlier this year, it had been 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 over half believing vaping was only as harmful as cigarettes.
Studying 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 in these already very bad numbers…those incorrectly believing e-cigs were just as harmful or worse than cigarettes had risen from 39.8% to 55.4%.” The information is available in the same week the American Cancer Society (ACS) admitted the American public has been misinformed about the risks of vaping – and is also now likely to promote it instead of smoking.
