A research letter that was published in the New England Journal of medicine in January of this year claimed that e-cigarettes produce levels of formaldehyde that exceeded those of tobacco cigarettes.

At the time, several scientists including cardiologist Dr Farsalinos refuted the study, citing that the research was not done in ‘real world conditions’. Dr Farsalinos has since undertaken further research on this subject, with his findings published today in the scientific journal Addiction.  These new findings clearly show that 3rdgeneration electronic cigarettes only produce high levels of aldehydes under extreme conditions.

Dr Farsalinos states,  “Our results verify previous observations that it is possible for e-cigarettes to generate high levels of aldehydes; however, this is observed only under dry puff conditions, which deliver a strong unpleasant taste that vapers detect and avoid, by reducing power levels and puff duration or by increasing inter-puff interval. Minimal amounts of aldehydes are released in normal vaping conditions, even if high power levels are used. In those normal-use conditions, aldehyde emissions are far lower than in tobacco cigarette smoke.”

Vapers are unable to tolerate dry puff conditions and adjust their devices accordingly.

Professor Peter Hajek commented on Dr Farsalinos’ findings stating, “These findings emphasise the importance of making clear the conditions in which tests of this kind are undertaken and avoiding sweeping assertions that can mislead the public. Vapers are not exposed to dangerous levels of aldehydes. My reading of the evidence is that e-cigarettes are at least 95% safer than smoking. Smokers should be encouraged to switch to vaping.”
