A new study found that third generation e-cigarettes (those with variable power settings) can produce higher levels of aldehydes but only under extreme conditions that smokers can be expected to avoid, according to Science Daily.
The Addiction study, led by cardiologist Dr Konstantinos Farsalinos, found that it was possible to get e-cigarettes to produce high levels of aldehydes, but only in what is known colloquially as ‘dry puff’ conditions.
As Farsalinos explains: “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.”
