Research Indicates E-Cigarettes Don’t Harm Lung Health Research Indicates E-Cigarettes Don’t Harm Lung Health

The long-term study concluded that there were no serious events correlated with vaping

The Regulatory Toxicology and Pharmacology Journal published a study by a team at the Research and Development Center in Liverpool England. This Team was lead by Tanvir Walele who happens to be the Director of Scientific Affairs for Fontem Ventures. Fontem Ventures is a division of Imperial Brands LLC, better known as the makers of Blu e-cigarettes.

This study set out to understand the long-term effects vaping has on lung function. Reduced lung function is, of course, the most common side effect of smoking traditional cigarettes. The study took place over two years, and the published results are very promising for those wondering if e-cigarettes are safe over the long haul.

Lung Function Report

Vaporizers, more specifically a device called Puritane was given to 209 smokers who were otherwise healthy. According to researchers, the Puritane is “representative of a typical closed system Electronic Vapor Product.” The participants were not asked to quit smoking entirely, as long as the used the vaporizer 80% of the time. This was to keep the results of the study realistic as many people are dual users at first. The participants were told to use only the Puritane vaporizer for 24 months.

Before beginning use of the vaporizer, participants were run through a series of tests to get a baseline for the study. They were tested for abnormalities in their vital signs, spirometry, and electrocardiogram, which they all passed. During the first phases of the study, some participants reported mild side effects with 28.7% reporting headaches, 19.6% reporting sore throats and 16.7% reporting a cough. The Majority of these issues went away after a few weeks on the vaporizer. Nicotine withdrawal symptoms dropped off rapidly at the two-month mark. At that same point participants that had been dual users of the vaporizer and cigarettes were decreasing their use of conventional cigarettes, with many of them outright quitting.

At the end of the 24-month study around half of the initial 209 participants had completed the full trial. Tested again, these participants showed no adverse changes. There were no adverse effects in biomarkers of hematology or lipid metabolism. Researchers found that “the frequency of adverse events steadily decreased throughout the study.” The fact that the adverse effects decreased and there was a complete lack of damage to lung function shows the legitimacy of vaporizers and e-cigarettes as a long-term smoking cessation tools.

Further Study

There are many studies, this one included, published in the past few years that support the belief vaping is a fantastic smoking cessation and harm reduction tool. A study published by researchers at the University of Louisville found that between several different common cessation tools, vaping was the most successful, even beating out prescription drugs.

Another study done in partnership between Columbia and Rutgers Universities found that 52% of the participants quit smoking for good with the help of daily vaping. In the same study, they found that those who only vaped some days were only successful at stopping 12% of the time. All these studies share the conclusion that vaping can play a significant roll in helping smokers quit.

Implications

Some individuals may feel there is bias in a study performed by workers from the vaping industry, which is a perfectly valid stance. But this study was published in a well-respected peer review journal, so the findings should be treated accordingly. Purely and simply, it means the science makes sense. This study is also supported by many of the other, unbiased, studies on the same topic that have taken place in recent years.

If you can look past the potential bias, you’ll see this research as another piece of methodical evidence that supports the conclusion that vaping is substantially safer than smoking. A study carried out by England’s federal health organization, Public Health England, concluded that vaping is at minimum 95% safer than smoking. Multiple other studies that weren’t referenced in this article also reached very similar conclusions about the relative risks of vaping and smoking.

Long-term studies such as this are beginning to answer questions about what consistent usage of vaporizers and e-cigarettes does to the body. Therefore these studies are and will continue to be extremely critical to the public perception of vaping. They are the best defense against the consistently negative view of vaping portrayed by the media. So if we want to support vaping for its smoking cessation and harm reduction value, we must spread positive research like this.

Did you have any side-effects when first making the switch? Do you know anyone who experienced symptoms like those listed? Are studies funded by biased parties legitimate if the research is solid?
