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 in 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 within 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 research is among the first detailed studies conducted to analyze the dynamic properties of exhaled e-vapour aerosol particles. The study entitled “Characterisation from the Spatial and Temporal Dispersion Differences between Exhaled electronic cigarette mist and Tobacco 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.
Throughout the study, Vapor Cigarettes used commercially available closed and open system vaping products while researchers measured particle concentrations in the surrounding air. Unlike for conventional tobacco smoke, following immediate exhalation, scientists observed a rapid decay and evaporation in the liquid aerosol droplets, with levels returning to background levels within a few moments. This was also observed under no room ventilation conditions, representing a worst 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 adds to the growing body of evidence that vaping indoors is unlikely to pose an air quality issue,” said Dr O’Connell.
Both 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 few seconds; for conventional cigarettes it increased with successive puffs, only going back to background levels after 30-45 minutes.
HE variety of vapers are falling in the usa, 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, based on the latest National Health Interview Survey (NHIS), that was one million less than the prior year.
The survey, the source for that Centers for Disease Control and Prevention’s (CDC) national smoking estimates (the nation’s health protection agency), it can make the quantity of current vapers two million fewer than in 2014, the first year NHIS surveyed for vaping.
Data also showed the number 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 have the switch away from their deadly habit, are now concerned misinformation inside the public domain about vaping has seen the number of vapers tragically decline.
Long-time vaping campaigner, Clive Bates, said of the news: “American anti-vaping extremists are doing well in fighting off the vaping threat for the cigarette trade,” while Gregory Conley, president of the American Vaping Association, thought more should be completed to educate smokers about the advantages of vaping and correct the misinformation they are fed.
He stated pursuing the recent data – which showed not only 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 as opposed to ~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 through the National Cancer Institute’s Health Information National Trends Survey (HINTS), had risen, with over half believing vaping was only as harmful as cigarettes.
Looking at the numbers from 2013 to 2017 (available here), Bates said: “So what difference did four 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 like harmful or worse than cigarettes had risen from 39.8% to 55.4%.” The information will come in the same week the American Cancer Society (ACS) admitted the American public has become misinformed regarding the dangers of vaping – and it is now going to market it instead of smoking.
