A 2015 study analyzing 10 puffs found that vaping at a high voltage (5.0 V) generates formaldehyde in e-cigarette vapor; they inferred from the finding that the user vaping at high voltage with 3 ml of e-liquid daily would inhale 14.4±3.3 mg of formaldehyde daily in formaldehyde-emitting chemicals.

Smoking e-cigarettes delivers cancer-causing chemicals into the body — and popular fruity flavors appear to be the worst offenders.
Although e-cigarette aerosols don’t have the same cancer-causing contaminants as tobacco smoke, people still breathe in chemicals when they vape, and this study shows that it has an effect on ...
In addition to containing varying levels of the addictive substance nicotine, they also contain other cancer-causing chemicals, such as formaldehyde, and as our study shows, flavoring chemicals ...
Tobacco smoke contains 100 known carcinogens and 900 potentially cancer-causing chemicals, but e-cigarette vapor contains less of the potential carcinogens than found in tobacco smoke. [125] A study in 2015 using a third-generation device found levels of formaldehyde were greater than with cigarette smoke when adjusted to a maximum power ...
In 2021, researchers at Johns Hopkins University analyzed the vape aerosols of popular brands such as Juul and Vuse, and found "nearly 2,000 chemicals, the vast majority of which are unidentified." [ 24 ] E-cigarette vapor contains many of the known harmful toxicants found in traditional cigarette smoke , such as formaldehyde , cadmium , and ...
Cigarettes contain tobacco, tar and a range of other toxic cancer-causing chemicals, and are one of the largest preventable causes of illness and death in the UK.
Metabolism and chemical binding to DNA (adduct formation) are critical in cancer induction by NNK and NNN. Human metabolism of NNK and NNN varies widely from individual to individual, and current research is attempting to identify those individuals who are particularly sensitive to the carcinogenic effects of these compounds.
