The researchers tested the biological system using known irritants in liquid form. Later they exposed the EpiAirway tissues to traditional cigarette smoke or e- liquid aerosol generated from one of two types of commonly available e-cigarettes for up to six hours. During testing, cell viability was measured using an established colourimetric test in 1 hour intervals.
Test results show that traditional cigarette smoke reduces cell viability to 12% (almost complete cell death) after six hours. At the same time, neither of the e-liquid aerosols showed any significant decrease in cell viability. Even after 6 hours of continuous, aggressive exposure, the results of e-cigarette vapours were nearly exactly the same as in test cells exposed to clean air only.
Hopefully this research (available HERE) will help bring the argument of “e-cigarettes being more harmful than analog cigarettes” to an end as it is another strong proof showing the opposite. Especially one conducted by a big player in the tobacco industry. It is also (with recent BAT’s actions) a clear statement that the company is clearly moving to the light side of The Force.
Are we afraid of competition? Actually, it is the opposite – an asset to the industry with huge potential in both the development and legal side of the e-cigarette and e-liquid manufacturing has joined the battle. We hope that the presence of such a well-known, established company will not only help progress the industry even further but will also help convince both tobacco and medical companies, peers, and researchers of the health benefits related to vaping as opposed to smoking traditional cigarettes.
