A new peer-reviewed study published in the prestigious journal Nicotine & Tobacco Studies have shown that exhaled e-vapour product particles are actually liquid droplets that evaporate within 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 time periods,” said Dr Grant O’Connell, Corporate Affairs Manager at Fontem Ventures, and senior author of the study.
The investigation is among 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 Cigarette 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.
Throughout the study, Liquid Vapor Cigarette 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 fast decay and evaporation in the liquid aerosol droplets, with levels returning to background levels within a few moments. 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 tobacco 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 air quality issue,” said Dr O’Connell.
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 in a matter of moments; for conventional cigarettes it increased with successive puffs, only going back to background levels after 30-45 minutes.
HE number 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 been 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 was one million less 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 quantity of current vapers two million fewer than in 2014, the very first year NHIS surveyed for vaping.
Data also showed the quantity 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 aiding smokers have the switch from their deadly habit, are now concerned misinformation inside the public domain about vaping has seen the amount of vapers tragically decline.
Long-time vaping campaigner, Clive Bates, said in the news: “American anti-vaping extremists are performing well in fighting off the vaping threat to the cigarette trade,” while Gregory Conley, president of the American Vaping Association, thought more needed to be done to educate smokers about the benefits of vaping and correct the misinformation they have been fed.
He stated after 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 might be even lower today.”
Earlier this season, it was 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 more than half believing vaping was only as harmful as cigarettes.
Exploring 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 equally as harmful or worse than cigarettes had risen from 39.8% to 55.4%.” The info comes in the same week the American Cancer Society (ACS) admitted the American public has been misinformed regarding the hazards of vaping – and it is now planning to promote it as an alternative to smoking.
