In a recent study, scientists have found electronic cigarette vapor has NO toxic effect on the cells found in human lungs. Fresh research, funded by British American Tobacco (BAT), suggested inhaling nicotine vapor could be as safe as breathing air.
To perform these experiments, the tobacco giant teamed up with the MatTek Corporation, maker of human cell models used in “in vitro” laboratory experiments. Scientists then used a “smoking robot” to expose these lung cell replicas to tobacco smoke, two different brands of e-cig vapor, and plain old air.
After being exposed to old-fashioned smoke for six (6) hours, the cells died. However, after subjecting the cells to an “aggressive and continuous” dose of e-cig vapor, researchers claimed the damage to the airway tissue was “similar to that of air”. BAT spokesperson, Dr Marina Murphy, stated “by employing a combination of a smoking robot and a lab-based test using respiratory tissue, it was possible to demonstrate…. the e-cigarette aerosols used in this study have no [toxic] effect on human airway tissue.”
