A new report, published by cardiologist Dr Konstantinos Farsalinos in online journal Addiction, has revealed that e-cigarettes can only produce harmful levels of formaldehyde which exceed those of regular cigarettes under ‘extreme conditions’.
It was discovered that it was only possible to create high levels of carcinogenic aldehydes if a vaper used third-generation e-cigarette (an e-cigarette with variable power settings) and repeatedly ‘dry-puffed’ on it – an unpleasant experience which most vapers avoid.
Dry-puffing is done by reducing power levels and puff duration or by increasing intervals between puffs, which is reported to have a bad taste, make you cough, and leave behind traces of e-liquid in your mouth.
Dr Farsalinos carried out the study under real-world conditions, finding that the production of aldehydes was not apparent in these cases, and was only found when vapers used the ‘dry-vaping’ technique. He also added that although very small amounts of aldehyde were created when vaping under normal conditions, these emissions are much, much lower than those from regular cigarette smoke.
