More than 50,000 lives could be saved each year if all British smokers switched from cigarettes to e-cigarettes, experts say.
Researchers from University College London (UCL) estimated that for every million smokers who switch from tobacco to electronic cigarettes, over 6,000 premature deaths would be prevented each year in the UK.
There are around nine million British smokers and if they all switched to the the nicotine vapour inhalers instead of the tobacco products they currently use, around 54,000 lives could be saved.
The experts said the reduced mortality rate even accounts for the possibility that e-cigarettes may carry an increased risk of death.
