Different opinions on the risks of using Electronic Cigarettes

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."

Based on the calculations made by Dr. Konstantinos Farsalinos (principal investigator of the e-cigarette) from the data provided in the article, the resistance did not exceed 1.7 ohms. At a voltage of 5.0V, the power would be 14.7W. That's in the "red zone," where the vaporizer is overheated and where, for a conventional e-cigarette, the coils are likely to be damaged or burned.

In essence, what this study shows is that if you overheat a vaping system, it will produce high levels of formaldehyde. However, such conditions are not realistic, as they could not be tolerated by a real vaper. Therefore, extrapolating this study to a vaping life does not make sense. We do not believe that there is an ecig with these electrical characteristics in the market.

The researchers extrapolated anyway, estimating that vapers could face a risk of formaldehyde-related cancer "5 times higher ... or even 15 times higher ... as the risk associated with long-term consumption . " Later, more than one of the researchers acknowledged that such speculation was a bit premature. "It's too early now from an epidemiological point of view to say how bad (e-cigarettes) they are," said James Pankow, a professor of chemistry and engineering at Portland State University in Oregon, in an interview with NBC News. "But the bottom line is that there are toxins, and in some cases they are more than normal cigarettes. And if you are in vaping, you probably should not be using it in a high-voltage environment."

The implication that vapers in the real world are apt to generate levels of formaldehyde similar to those generated by Pankow et al. With "La Máquina" is very deceptive. "With the creation of their equipment to repeatedly take puffs of three to four seconds at 5.0 volts, researchers have overheated the vaporizer," says Bill Godshall, CEO of Smokefree Pennsylvania. "Vapers call this the" dry leaf phenomenon "and do not do so because of the very hard and horrible taste.When making a false assumption and multiplying that false assumption of one and the other, the researchers have it all wrong.There is no scientific evidence That e-cigs increase the risk of cancer or any other disease. "

Pankow told NBC "We are not saying that electronic cigarettes are more dangerous than cigarettes," although that is the impression left by the NEJM letter. He pointed out that "we are only dealing with a chemical" of the thousands that are in the tobacco smoke, of which hundreds are toxic or carcinogenic. "The jury is really not sure how these drugs are," he said. According to Reuters, "Pankow admitted that the study could have contained more context about global relative risk, but said the authors" just wanted to publish it as soon as possible. "

In conclusion, it is very likely that you will never find an electronic cigarette in the market with the electrical characteristics of the experiment, therefore, you will never be exposed to those levels of formaldehyde, and surely if you feel that the taste of your steam changes He would immediately stop vapouring. What do you think?
