New flavors has prompted smokers to shift to e-cigarettes in the recent days. A number of people believe that e-cigarettes are less harmful as compared to normal cigarettes. However, medical practitioners and analysts disagree with this precept on several grounds. A recent research points to increased risks of cardiovascular diseases due to consumption of e-cigarettes. The research conducted at Stanford University’s School of Medicine gives key insights related to smoking of e-cigarettes. Electronic cigarettes are blended with flavouring liquids that mellow down the smoking strength. However, the researchers also found these liquids to increase the risk of cardiac problems. The research has created ripples across several organisations that run smoking cessation campaigns.
Effect on Endothelial Cells
Researchers studied the impact of e-cigarette liquids on endothelial cells present inside the blood vessels. Further, they found that these liquids significantly damaged the inner lining of the blood vessels. Furthermore, the liquids were also responsible for the ultimate death of the blood cells. The researchers concluded that e-cigarette liquids inhibited the migration of cells which in turn restricted wound-healing. Hence, even in the absence of nicotine, e-cigarettes could severely impact human health. Menthol and cinnamon are amongst the most harmful flavours for the cardiovascular health of individuals.
The researchers stated that the new study helped them in discovering the impact of e-cigarettes on endothelial cells. They further asserted that e-cigarettes are not a viable alternative for cigarette smoking. The research could be a landmark in ensuring that e-cigarettes receive as much flak as normal cigarettes.
In a recent study on the e-cigarette, shows that the vapor emitted increases the production of inflammatory chemicals and incapacitates key protective cells in lungs. The key cells in lungs helps in keeping the air spaces clear from expected harmful particles and innate immune system, as per the study published in Thorax journal. The vapor generated from e-cigarettes damages the alveolar macrophages, which protects lung alveoli from bacteria, dust, and allergens got escaped form respiratory tract. As per the findings of this research states that the e-cigarettes are more harmful and have similar effects seen in regular smokers or people suffering from chronic lung disease.
Furthermore, the demand for vaping is increasing; current researches are mainly focused on understanding the chemical composition of e-cigarette liquid afore it is vaped. To have a clear idea of the effect of vapor (condensate or through vaping) the researchers experimented by using extracted alveolar macrophages from non-smokers and those who do not have chronic obstructive pulmonary disorder. According to results, condensate was more harmful than e-cigarette fluid and it worsened as the dose was increased.
It also showed that condensate increased cell death and grown the production of oxygen free radicals and boosted the production of inflammatory chemicals more so with the presence of nicotine. Thus, showing that vaping process damages vital cells present in immune system, at least in the laboratories.
Therefore, the efficiency of cells when exposed to vaped condensate that engulfed bacteria were certainly damaged. Although with the help of treatment with the use of antioxidant restored its functions and reduced the harmful effects to a certain degree.
Even after smoking just one e-cigarette containing nicotine, healthy non-smoking people were found to develop a biological market that is known to raise the risk of heart disease in regular tobacco user, as per the new study. The study published in ‘Journal of the American Heart Association’ showed that nicotine is not as harmless as it seems and can impact the health of a smoker in multiple ways, and not just simply triggering addiction.
The introduction of e-cigarettes is fairly new and thus, its long-term effects are yet to be fully discovered. And the science community has had different sets of opinion about the safety of e-cigarettes. Recently, a renowned medical research group in UK suggested that tobacco switchers can shift to e-cigs in order to quit, but on the contrary, the US Centers for Disease Control and Prevention announced that there’s hardly any evidence to prove that e-cigs do help as tool for smoking cessation. At the same time, the body of study on health risk is gradually increasing. A study conducted in 2015 found that the vapor of e-cig causes damages to the immune system of mice. Last year, another study discovered that e-cigs creates 31 hazardous chemicals, including some that may lead to causing cancer.
Researchers believe, that such studies will challenge the beliefs of nicotine being a benign substance and does not possess a considerable health risk. For people who regularly smoke, a shift to e-cigarettes is good, as they have less carcinogens in orders of magnitude compared to regular cigarettes. However, for non-smokers it is strongly advisable not to start smoking with electronic cigarettes.
