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 in seconds. “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 periods of time,” said Dr Grant O’Connell, Corporate Affairs Manager at Fontem Ventures, and senior author of the study.
The research is probably the first detailed studies conducted to investigate the dynamic properties of exhaled e-vapour aerosol particles. The research entitled “Characterisation in the Spatial and Temporal Dispersion Differences between Exhaled electronic cigarette mist and Tobacco Smoke,” had been 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.
Through the study, Liquid Vapor used commercially available closed and open system vaping products while researchers measured particle concentrations within the surrounding air. Unlike for conventional cigarette smoke, following immediate exhalation, scientists observed a rapid decay and evaporation in the liquid aerosol droplets, with levels going back to background levels in seconds. This is also observed under no room ventilation conditions, representing a worst scenario.
“Exhaled e-vapour aerosol particles possess a different chemical composition to tobacco smoke and here we show the physical properties are also significantly different. This data increases 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 within 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 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 continues to be worryingly effective. About 6.9 million Americans were current users of e-cigarettes in 2017, according to the latest National Health Interview Survey (NHIS), which was millions of fewer than the earlier year.
The survey, which is the source for your Centers for Disease Control and Prevention’s (CDC) national smoking estimates (the nation’s health protection agency), it makes the quantity of current vapers two million fewer than in 2014, the very first year NHIS surveyed for vaping.
Data also showed the number 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 helping smokers have the switch away from their deadly habit, are now concerned misinformation in the public domain about vaping has seen the quantity of vapers tragically decline.
Long-time vaping campaigner, Clive Bates, said from the news: “American anti-vaping extremists are performing well in fighting off the vaping threat towards the cigarette trade,” while Gregory Conley, president from the American Vaping Association, thought more must be completed to educate smokers about the benefits of vaping and correct the misinformation they have been fed.
He stated following the recent data – which showed not only a decline in vapers but an all-time drop in smokers: “We’re typically reaching all-time low smoking prevalence. If 80% of Americans knew vaping was less hazardous rather than ~40%, we could be even lower today.”
Earlier this coming year, it was revealed Americans’ perception of the relative harm of e-cigarettes versus cigarettes, as measured from the National Cancer Institute’s Health Information National Trends Survey (HINTS), had risen, with over half believing vaping was just 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 like harmful or worse than cigarettes had risen from 39.8% to 55.4%.” The info comes in the identical week the American Cancer Society (ACS) admitted the American public has been misinformed concerning the risks of vaping – and it is now going to market it as an alternative to smoking.
