Vapor Safety Study: Vaping and The Human Respiratory Tissue
Late last month, a new study was quietly released that may prove to be the most major addition yet to the canon of research lending scientific support to the notion many vapers have long held that vaping is far safer than smoking.
Granted, the source – British American Tobacco, one of the five largest tobacco manufacturers in the world – may seem suspect. But the results, if they're able to be verified in future studies, are groundbreaking.
"By employing a combination of a smoking robot and a lab-based test using respiratory tissue, it was possible to demonstrate the ability to induce and measure aerosol irritancy and to show that the different e-cigarette aerosols used in this study have no cytotoxic effect on human airway tissue," says Big Tobacco spokesperson Dr. Marina Murphy.
Scientists took a 3D model of human respiratory tissue and connected one sample to a cigarette-smoking robot for six hours straight, then did the same using two different types of e-liquid vapor. While the smoke reduced the cells in the tissue to 12% viability (near complete cell death), there was no discernible effect on the cells exposed to the vapor.
In other words, even if you were to chain-vape for six straight hours, the study says your lungs would be no different than if you'd breathed normal air. But try to inhale a drag of smoke with every breath, and you're probably dead well before that – the cells exposed to tobacco dipped below 50% viability somewhere between the three and four hour marks.
Obviously, no one is going to vape (or smoke) in this manner. The study was designed to push the limits of reason, just like vaping studies produced by vape opponents that force their robots to take dry hits and inhale burning wick instead of vapor in order to report the presence of chemicals that wouldn't typically be found in a vapor cloud. Still, the fact that no ill effects could be identified even when condensing what's likely several days' worth of vaping into a few hours is promising.
The study is interesting in that it's being published by a big tobacco manufacturer despite the fact it's damningly anti-tobacco. One of the lead scientists, however, is billed as heading British American's "next generation nicotine products" division, which seems to suggest even Big Tobacco is coming to terms with the fact that its reign of death is coming to an end. Welcome to the club.
