Vaping e-cigarettes causes the build-up of chemicals known to cause harmful DNA mutations – and could lead to mouth cancer, experts have warned.

Researchers found that a 15-minute vaping session led to three carcinogens building up in people’s saliva, an as-yet-unpublished trial found.

The researchers found that vapers showed signs of DNA damage from a chemical, acrolein, which is produced when vape ingredient glycerol breaks down in heat.

The researchers found that three chemicals – formaldehyde, acrolein, and methylglyoxal – built up in people’s mouths after vaping.

Dr Silvia Balbo, from Masonic Cancer Centre in Minnesota said, ‘Comparing e-cigarettes and tobacco cigarettes is really like comparing apples and oranges. The exposures are completely different.

‘We still don’t know exactly what these e-cigarette devices are doing and what kinds of effects they may have on health, but our findings suggest that a closer look is warranted.’
