Electronic cigarettes pump out vapour which has NO toxic effect on the cells found in human lungs, scientists have claimed.
Research funded by British American Tobacco
has suggested inhaling nicotine vapour could be as safe as breathing air.
To perform its experiments, the tobacco giant teamed up with the MatTek Corporation, which makes models of human cells used in ‘in vitro’ laboratory experiments.
Scientists then used a “smoking robot” to expose these lung cell replicas to tobacco smoke, the vapour from two different brands of e-cig and just plain old air.
When exposed to old-fashioned smoke for six hours, the cells died.
But after subjecting the cells to an “aggressive and continuous” dose of vapour, researchers claimed the damage to the airway tissue was “similar to that of air”.
