E-cigarette Vapor Doesn’t Contain Toxic Formaldehyde According to CDC Study

E-cigarette Vapor Doesn't Contain Toxic Formaldehyde

A paper published in January 2015 in the New England Journal of Medicine (NEJM) led to false claims saying that second-hand e-cigarette vapor contains toxic levels of formaldehyde.

Sadly, some renowned researchers, including Dr. Konstantinos Farsalinos, have already refuted those claims and explained that the experimental processes used in the 2015 study were clearly inappropriate. Their explanations, however, have been ignored as this misinformation has been informing policy and scaring the public ever since.

Recently, the extensive researches by several public health experts all show that the levels of formaldehyde in e-cigarette vapor are insignificant to our health. A study by the U.S. Centers for Disease Control and Prevention (CDC) confirms these findings.

The Research Results of CDC on E-cigarette Vapor 

According to what Farsalinos and his colleagues had found, the recent study from the CDC has showed that e-cigarette vapor contains no more formaldehyde than the average American household does on a daily basis. In fact, many homes may possibly have much higher levels because of the textiles are common in homes, such as carpets and curtains.

The paper, which is titled Evaluation of Chemical Exposures at a Vape Shop, was published on the site of CDC. Researchers at the CDC collected their data through collecting air samples from vape stores. At vape stores, customers and employees are actively using e-cigarettes. And, not surprisingly, they found that the air quality tests did not produce measurable concentrations of formaldehyde or other toxins, even though the higher-than-average amount of vaping would be taking place in such outlets.

Consistent with the above, in 2017, the California Department of Public Health (CDPH), also carried out air sampling at vape shops across the state. On his blog, Public Health Expert Dr. Michael Siegel shared the results from a relatively small and non-ventilated vape store, in which many employees and thirteen customers were actively vaping when the air sampling was conducted, hence what would be seen as a situation that presents a high level of exposure to secondhand vapor.

In spite of these adverse conditions, results from this vape store still reported no dangerous levels of exposure to any hazardous chemicals. Sadly, the CDPH did not release this official data.

Both the public health experts and vaping advocates hope that the CDC study will get enough attention it deserves, and hopefully start repairing the damage done by the inaccurate and often quoted 2015 study.
