Vaping can damage vital immune system cells and may be more harmful than previously thought, a study suggests.
Researchers found e-cigarette vapour disabled important immune cells in the lung and boosted inflammation.
The researchers “caution against the widely held opinion that e-cigarettes are safe”.
However, Public Health England advises they are much less harmful than smoking and people should not hesitate to use them as an aid to giving up cigarettes.
The small experimental study, led by Prof David Thickett, at the University of Birmingham, is published online in the journal Thorax.
