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 compared to those released when smoking conventional cigarettes, the latter of which linger in the air for longer time periods,” said Dr Grant O’Connell, Corporate Affairs Manager at Fontem Ventures, and senior author of the study.
The investigation is probably the first detailed studies conducted to research 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,” 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 inside 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 returning to background levels in seconds. It was also observed under no room ventilation conditions, representing a worst case scenario.
“Exhaled e-vapour aerosol particles have a different chemical composition to cigarette smoke and here we show the physical properties will 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.
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 in 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 united states, 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), which was one million fewer than the previous 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 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 assisting smokers create the switch far from their deadly habit, are concerned misinformation within the public domain about vaping has seen the quantity of vapers tragically decline.
Long-time vaping campaigner, Clive Bates, said in the news: “American anti-vaping extremists are doing well in fighting off of the vaping threat to the cigarette trade,” while Gregory Conley, president in the American Vaping Association, thought more needed to be done to educate smokers about the advantages of vaping and correct the misinformation they have been fed.
He stated following 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 season, it had been revealed Americans’ perception 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 more than 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 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 data is available 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 going to promote it as an alternative to smoking.
