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 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 research is among the first detailed studies conducted to research the dynamic properties of exhaled e-vapour aerosol particles. The analysis entitled “Characterisation in the Spatial and Temporal Dispersion Differences between Exhaled e-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.
During the study, Best Vapor 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 fast decay and evaporation of the liquid aerosol droplets, with levels going back to background levels within seconds. It was also observed under no room ventilation conditions, representing a worst case scenario.
“Exhaled e-vapour aerosol particles possess a different chemical composition to cigarette smoke and here we show the physical properties can also be significantly different. This data increases 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 within the same order of magnitude. However, for e-vapour products the particle concentration returned to background values within a matter of moments; 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 united states, shock new data has revealed, proving its portrayal 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, according to the latest National Health Interview Survey (NHIS), which had been millions of fewer than the previous year.
The survey, which is the source for that Centers for Disease Control and Prevention’s (CDC) national smoking estimates (the nation’s health protection agency), it makes the amount of current vapers two million less than in 2014, the initial year NHIS surveyed for vaping.
Data also showed the amount 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 concerned misinformation in 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 in the American Vaping Association, thought more needed to be completed to educate smokers about the advantages of vaping and correct the misinformation they have been fed.
He explained after the recent data – which showed not simply 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 as opposed to ~40%, we could be even lower today.”
Earlier this coming year, it absolutely was 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 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 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 regarding the risks of vaping – and is also now planning to market it instead of smoking.
