A letter published by the New England Journal of Medicine yesterday reported a study in which researchers analyzed the aerosol produced by an e-cigarette tank system (a rechargeable vaporizer with a variable voltage battery) and "did not detect the formation or Release of any formaldehyde ". Of course, you may think that this finding immediately seized the attention of the media throughout the country, which would lead to headlines like "No formaldehyde in the vapor of Ecig" and "study confirms that Vaping is more secure Than smoking. "
But no. For some reason, journalists clung to another of the same study results, suggesting that a vaper could inhale more than four times the amount of formaldehyde as a smoker a pack-a-day. That SI finding made headlines such as "e-cigarettes can produce more formaldehyde than regular cigarettes, and" the study says that e-cigarette vapor is full of cancer-causing chemicals, according to researchers.
Well, according to the researchers, the difference between dramatically different results was the voltage (voltage) scenario. At low stress, the tank system did not produce formaldehyde, however, at high stress, a large amount of formaldehyde is produced. But as Michael Siegel, a professor of public health at Boston University, pointed out in his political blog about tobacco, the conditions in the last test were not realistic, leading to overheating that would make a human vaper, unlike Of a machine, stop overturning.
The power that was used was so high that the vaporizer overheats ... creating a horrible flavor that a vaper could not tolerate. This is sometimes referred to as the "dry blow phenomenon."
