E-cig smokers may be exposing themselves to high levels of cancer causing chemicals, according to new research.
Benzene, found in traffic pollution and paint stripper, has been linked to a number of diseases including leukaemia and bone marrow failure.
Now scientists have found that levels can form in the vapours of the devices when they are operated at high power.
These are much higher than those found in the surrounding atmosphere – which have been linked to increased cancer risk.
The higher an e-cig’s voltage, the greater the resulting amount of vapour. This means a stronger throat hit and more intense taste.
