Hidden formaldehyde in e-cigarette aerosols Read the study
This study looked for formaldehyde-releasing agents (called formaldehyde hemiacetyls) in e-cigarettes vapour. The devices were tested at both a low and a high voltage.
What it Found
At low voltage, formaldehyde hemiacetyls were not detected, but at high voltages they were. Based on the high voltage results, the authors calculated that the risk of cancer from vaping could be 5 to 15 times higher than from cigarettes.
This study led to headlines such as “E-cigarettes can churn out high levels of formaldehyde.”
What’s Wrong With it?
The core problem with this study is that the combination of voltage setting and atomizer used would invariably lead to “dry puffs.” These taste extremely unpleasant and don’t represent real-world use of e-cigarettes. This point has been confirmed by later research.
At the usable setting, the chemicals were not even detected.
It’s like turning a toaster up to the maximum setting, measuring the carcinogens on the surface of the charred bread that pops out and then concluding that eating toast is a significant risk for cancer. The big problem is that nobody eats cremated toast.
