They're often portrayed as safer alternatives to cigarettes, but a new study has revealed thatelectronic cigarettesmay be more dangerous than thought.

Researchers from theUniversity of Minnesotahave revealed that vaping can damage theDNA in your mouth, which in turn, increases your risk ofcancer.

Dr Silvia Balbo, who led the study, said: "It's clear that more carcinogens arise from the combustion of tobacco in regular cigarettes than from the vapor of e-cigarettes.

"However, we don't really know the impact of inhaling the combination of compounds produced by this device.

"Just because the threats are different doesn't mean that e-cigarettes are completely safe."

In the study, five e-cigarette users provided saliva samples before and after a 15-minute vaping session.

The researchers analysed these samples for chemicals that are known to damage DNA, and also assessed DNA damage in the cells in the volunteers' mouths.

The results revealed that the levels of three DNA-damaging compounds - formaldehyde, acrolein and methylglyoxal - increased in the saliva after vaping.

And compared with people who don't vape, four of the five e-cigarette users showed increased DNA damage related to acrolein exposure.

This type of damage, called a DNA adduct, occurs when toxic chemicals react with DNA.

Worryingly, if the cell does not repair the damage, it could lead to cancer, according to the researchers.

The team now plans to replicate the study on a larger scale, to see how the level of DNA adducts differs between e-cigarette users and regular cigarette users.

Dr Balbo 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."
