It is common known that smoking tobacco is a nasty habit that can negatively influence both one’s personal health and the health of those around that individual. In order to create a healthier option, while still maintaining that ‘tobacco hit’, researchers have developed items known as electronic cigarettes. Yet, the smoking of these electronic cigarettes, also known as vaping, has recently received criticism. This is due to people feeling that the inhalation of any substance, other than oxygen, is not beneficial to one’s health. This article will provide information on the research conducted to determine the effects of smoking compared to vaping.
Studies completed by scientists at the British American Tobacco corporation have found that the human respiratory tissue is beneficially affected by electronic cigarette vapor. In fact, studies showed that the inhalation of electronic cigarette vapor is quite similar to the inhalation of air; thus it is considered to be non-threatening and non-toxic. The vapor tested was taken from two separate types of electronic cigarettes and both showed the same health benefiting results.
Researchers from the British American Tobacco corporation and the MatTek organization completed further tests to determine the potential adverse effects of electronic cigarettes. While findings showed that exposure to tobacco smoke is more detrimental than vaping, further negative consequences were considered.
Dr. Marina Murphy, a representative of both organizations indicated that the tests were completed using a combination of smoking robots and a lab-based measure to determine the consequences on human respiratory tissue. As the test could not induce or measure aerosol irritancy, it can be concluded that the vapor in e-cigarettes does not have a cytotoxic effect on the respiratory system.
The research discussed above utilized a 3D model of the human respiratory tissue, as well as the VITROCELL smoking robot. When placed together, an aerosol exposure system was used to measure the potential aerosol irritancy of e-cigarette vapors. The results indicated that irrespective of the hours of continuous exposure the vapor was non-toxic and similar to air.
The model created was utilized for the airway tissue known as EpiAirway, a system that comprises the human bronchial cells and cultivates them to form defined layers resembling an epithelial tissue in the human respiratory tract. The VITROCELL robot provided tobacco smoke and mimicked the effect tobacco can have on humans, both primary smoking and secondary smoking. The first round of testing examined the known irritants available in liquid form and then exposed the tissues to the smoke generated from various electronic cigarettes.
Before this research was conducted, it was not possible to locate studies into the effects of electronic cigarette vapor. The information gained is of vital importance as it can assist in developing e-cigarette products to help addicted smokers while maintaining health benefits. In fact, the overall findings indicated that reduced cell viability measured in at 12% after 6 hours of tobacco exposure.
As can be seen, using electronic cigarettes is far more beneficial and acceptable when compared to smoking traditional cigarettes. It is no surprise that more and more people are trading their traditional cigarettes in for electronic cigarettes and vaping pens. The research has provided a platform for future studies regarding the effect of vaping, but for now electronic cigarettes are increasing in popularity and is quickly becoming a worldwide phenomenon.
