British American Tobacco study suggests e-cigarette vapor does not cause cell death in human lungs
What long-term effect do e-cigarettes have on human lungs? That is the question that many, many researchers are trying to answer right now.
If researchers find that e-cigarettes have a minimal effect on the human lungs over time or if they find that e-cigarettes are significantly safer for human lungs that regular cigarettes, it would be a huge breakthrough and would give the entire vaping industry a big boost.
People would start to look at e-cigarettes in a completely different light, and over time, e-cigarettes would likely start to replace regular cigarettes more and more.
At the moment, researchers can’t definitively say that e-cigarettes are safer than regular cigarettes, but researchers at British American Tobacco—which is one of the largest tobacco companies in the entire world—conducted experiments recently and discovered that the vapor from e-cigarettes has a much different effect on the cells located in human lungs than the smoke from regular cigarettes.
They were quick to point out that additional research will need to be done in the future to confirm what they found, but their initial findings are, at the very least, encouraging for the vaping community.
They suggest that e-cigarette vapor does not cause oxidative stress or cell death in the lungs, which are two things that make regular cigarettes so dangerous. Continue reading to learn more about the important research done by British American Tobacco.
E-Cigarette Vapor – The Experiment
The goal of British American Tobacco’s study was to figure out how e-cigarettes and regular cigarettes impact human lungs in different ways. In order to test this, they came up with a standardized way to measure the amount of oxidative stress and cell death that takes place inside of the human lungs when cigarette smoke and e-cigarette vapor are put into them.
They used an in vitro model of lung epithelium and exposed lung epithelial cells to similar concentrations of smoke and vapor. Then, they took a look at the stress responses of the cells located within the lungs to see how they reacted to cigarette smoke and e-cigarette vapor.
They also exposed the lungs to different levels of smoke and vapor to see if they would react differently based on how much smoke or vapor exposure took place. By examining the lung cells that were exposed to cigarette smoke versus the lung cells that were exposed to e-cigarette vapor, they were able to draw some clear conclusions.
E Cigarettes – The Findings
After exposing the in vitro model of lung epithelium to cigarette smoke and e-cigarette vapor, the British American Tobacco researchers stumbled upon some interesting results.
They found that, regardless of how much cigarette smoke the lung cells were exposed to, they almost immediately started to show clear signs of oxidative stress. Additionally, cell death started to occur and cytotoxicity set in. It was fairly evident that cigarette smoke had a negative effect on the lung cells.
The same could not necessarily be said for the e-cigarette vapor, at least in the short term. When the lung cells were exposed to the vapor, even at very high levels, the lung cells did not show the same signs of oxidative stress and cell death.
The researchers used the highest concentration of e-cigarette vapor but were unable to reproduce the effects that the cigarette smoke had on the lung cells. The researchers pointed out that both the cigarette smoke and the e-cigarette vapor had similar levels of nicotine in them but that the vapor did not have many of the harmful chemicals present in the smoke.
Dr. Chris Proctor, who is the Chief Scientific Officer at British American Tobacco, spoke about the findings later. “These data suggest that exposure to vapor from the e-cigarettes tested induces negligible or no oxidative damage to lung epithelial cells at the range of doses tested,” he said. “This highlights the scale of difference in potency between e-cigarette vapor and cigarette smoke and adds to the weight of evidence on the reduced risk potential of e-cigarettes.”
E Cigarettes – The Future
While those who support vaping should be ecstatic about what British American Tobacco researchers found during their study, it’s still entirely too soon for anyone to say that e-cigarette vapor is, without a doubt, healthier than cigarette smoke.
As British American Tobacco pointed out, there is still so much research to be done, especially with regards to long-term effects that e-cigarette vapor could potentially have on lungs and other parts of the human body.
However, it’s definitely a step in the right direction and shows that additional studies should be done on cigarette smoke and e-cigarette vapor and the effects that they both have on human health.
They recently published a lengthy report and estimated that e-cigarettes could be up to 95 percent safer than regular cigarettes. Now, it’s time for organizations in the U.S. and other countries to take part in similar studies and run experiments on e-cigarettes to test them for their potential benefits. At this point in time, there simply cannot be enough research done when it comes to e-cigarettes.
At the end of the day, finding out more about the long-term effect that e-cigarettes have on human lungs will allow everyone from small vape shops to the FDA figure out how to proceed with regulating them.
As of right now, the lack of research has, in a lot of ways, impacted the vaping industry, and not necessarily for the better. But by learning more about vaping, researchers can help guide large organizations as they make important decisions about e-cigarettes, e juices, and more.
The study that was done by British American Tobacco is just one small step in the process, but it’s one of many steps that needed to be taken and it will hopefully lead to additional research in the future.
