Contrary to what a study presented in 2015, vaping would not be 5 to 15 times more carcinogenic than smoking! The resounding 2015 study on " hidden formaldehyde »E-cigarette liquids and their harmfulness has just been formally demonstrated by Greek researchers.
DR FARSALINOS TAKES THE STUDY ON FORMALDEHYDE IN VAPING!
A Greek study invalidates the idea that the aerosol of electronic cigarettes is 5 to 15 times more carcinogenic than the smoke of tobacco cigarettes. In 2015, in an alarming article that made the front page of the New England Journal of medicine, Paul R. Jensen and his fellow chemists at the University of Portland, in the United States, announced that they had measured worrying levels of formaldehyde, a carcinogen and respiratory toxicant formed when the aerosol was heated.
The announcement had sparked skepticism and controversy. The Portland researchers' measurement conditions were " unrealistic“, Demonstrate today Konstantinos Farsalinos and colleagues from the Onassis Cardiac Surgery Center, Athens, and the University of Patras in the journal Food and Chemical Toxicology.
Cardiologists and pharmacologists replicated the study using the same e-liquid and older generation e-cigarette equipment, with two different voltages, 3,3 volts and 5 volts. They asked 26 experienced vapers to take four second puffs at different voltage settings and monitor the generation of dry puffs those dry puffs that result from overheating, like milk on a fire ... These have a pungent taste so unpleasant that users easily spot them and avoid them.
LESS FORMALDEHYDE THAN IN TOBACCO!
The phenomenon of dry puffs was detected by 30% of participants from 4 volts and 88% of guinea pigs perceived it at 4,2 V. Konstantinos Farsalinos and his colleagues have therefore defined 4 V as " the realistic upper limit of use". And under these vaping conditions, the formaldehyde in the aerosol of e-cigarettes is much lower than that of conventional cigarette smoke.
At the maximum level of 4 V, the level of exposure to formaldehyde was 1005,4 μg / 3 g of e-liquid, which is 32% less than 20 smoked tobacco cigarettes, the Patras researchers measured by following the same protocol as the Portland chemists. At 5 V, an unrealistic voltage for an electronic cigarette user, the exposure level was 27151,5 μg / 3 g of liquid, which is 18,3 times higher than 20 smoked tobacco cigarettes.
« No vaper uses the electronic cigarette under these conditions and, therefore, will never be exposed to such levels of formaldehyde.“, Comments Konstantin Farsalinos. The story published in the New England Journal of Medicine is like finding carcinogens in a piece of charred meat that no one can ever eat! Findings are correct, but no one will be exposed to levels such as those seen in the study. For the researcher, to get to the laboratory a correct measurement of the products to which the vapers are really exposed, the dry flushes must no longer be generated.
