How much formaldehyde do e-cigs release?

Back in 2015, a ‘scientific study’ released results suggesting that heavy users of vape products were 15 times more likely to get cancer than a long-time smoker. This was based on research that tested for formaldehyde in vapour – a probable carcinogen.

Despite the outcry from scientists who saw the study for the hoax that it was, the ‘research’ had already done its intended damage and added yet another false argument to the anti-vaping debate.

In a new study, produced by none other than British American Tobacco, the real levels of formaldehyde in vaping have been released – and they fall well below what the World Health Organisation considers safe.

So low, in fact, that vaping has less than a sixth of what normal indoor air exposes us to.

The study measured formaldehyde levels produced from e-cigs, a clearomiser, and a closed system to cover all forms of vaping. In all cases, the highest voltage was used to create a ‘worst case scenario’ and produce as much formaldehyde as possible. Researchers based their results off what happens with 350 puffs per day to ensure ‘heavy use’ was accounted for.

Even then, the absolute worst results the researchers could produce in terms of formaldehyde levels was still more than 10 times less than what you could find in a standard cigarette.

Effectively, even the heaviest users of vape products can expect no more than a sixth of the formaldehyde you get from simply breathing normally indoors.

“We believe e-cigarettes hold a great potential for reducing tobacco-related disease. For this reason, we continue to strive to better define and further reduce any residual risks that there may be, to as low a level as possible,” explained Principal Toxicologist at BAT Sandra Costigan.
