A new study that claims e-cigarettes are far less harmful than regular cigarettes may have ulterior motives for their findings. The study was funded by a tobacco company that just recently started selling e-cigarettes.
In the study, researchers exposed human lung cells to e-cigarette vapor as well as traditional cigarette smoke in a lab setting. The cells were exposed to each for a 60-minute duration, which, according to the study, is comparable to how long smokers and vapers are exposed over the course of the day. The paper advises that the example was “relatively extreme compared to real-life human exposure.”
The study came to the conclusion that e-cigarette vapor was 70 to 97 percent less toxic than cigarette smoke.
The study sponosr, British American Tobacco, is one of the largest tobacco companies in the world, known for brands such as Lucky Strike and the Vype ePen. Although the study was published in a reputable peer-reviewed journal – Toxicology Mechanisms and Methods – contradictory research regarding the “safety” of smoking e-cigarettes raises doubts regarding the study’s objectivity.
However, another recent study advises that vaping can damage human DNA, leading to cancer, and says vaping has been linked to heart damage.
Another study suggests vaping increases susceptibility to infections, suppresses the immune system and causes gene changes that could lead to mental illness.
E-cigarette liquid has also been found to contain diacetyl, a flavoring agent that mimics the creamy taste of butter. The chemical has recently been linked to Alzheimer’s, as well as serious lung diseases such as bronchiolitis obliterans, where the smallest airways of the lungs have become inflamed and scarred, severely restricting airflow.
