According to a new research, led by Daniel J. Conklin, Ph.D., an assistant professor at the University of Louisville, electronic cigarettes may affect heart rate and function.
For the study, the scientists exposed healthy mice to electronic nicotine delivery systems (ENDS) for 9 minutes. In addition, the mice were exposed to smoke from traditional cigarettes with and without nicotine.
Having analyzed the received results, the authors of the study concluded that ENDS aerosols strongly affect cardiovascular function in mice. Also, the study revealed that the mice also showed an increased blood pressure.
A team of researchers from the University of Southern California finds that teenage users of e-cigarettes are twice more likely to get bronchitis compared to children who have never smoked electronic cigarettes.
For their study, the scientists analyzed the responses from more than 2,000 older teenagers, asking for symptoms of chronic bronchitis such as a daily cough for three months straight.
Researchers found that those teenagers who vape had 71% higher risk of the condition which was connected to the risk of damaging lungs.
Dr Rob McConnell, a professor of preventive medicine at the Keck School of Medicine, within the University of Southern California, says: “E-cigarettes are known to deliver chemicals toxic to the lungs, including oxidant metals, glycerol vapour, diketone flavouring compounds and nicotine. However, there has been little study of the chronic health effects of e-cigarettes.”
According to the new laboratory study from the US, flavourings used in electronic cigarettes can intensify the toxicity of the vapour inhaled by a user. Moreover, electronic cigarette vapour becomes more toxic when users upgrade their devices increasing the voltage of battery output.
Senior researcher Maciej Goniewich, an assistant professor of oncology at Roswell Park Cancer Institute in Buffalo, N. Y., says that the toxins in e-cigarette vapour irritate and inflame cells in the respiratory tracts and can cause or exacerbate breathing issues in some users.
Researchers suggest that their findings raise some concerns about safety of flavourings used in electronic cigarettes.
According to the recent study published in the journal Chest, chemicals in the vapour of E-cigarettes produce short-term signs of potential harm for the cardiovascular system.
Researchers note that the signs of harm were similar but lesser compared to those induced by smoking common cigarettes. They compared the effects of smoking and vaping with the same nicotine content on the blood vessels in volunteers. 40 healthy men and women, 20 smokers and 20 nonsmokers, participated in the study.
“Our study demonstrates that both cigarettes and e-cigarettes have unfavourable effects on markers of oxidative stress and FMD after a single use, although e-cigarettes appeared to have lesser impact”, study says. “Future studies are warranted to clarify the chronic vascular effects of E-cigarette smoking.”
Numerous studies suggest that electronic cigarettes used by many people as an effective smoking cessation aid are significantly less harmful to health than traditional cigarettes. However, the new study claims that these devices can put your health at risk too, they could lead to oral disease.
This study, published in the journal PLOS One, reveals that the vapour of e-cigarettes contains toxic compounds and nanoparticles that destroy outer layer of skin cells in the mouth.
On assessing the effects of electronic cigarette vapour on oral cavity cell cultures, the scientists found that the vapour reduced levels of glutathione within the cells, which is an important antioxidant that protects them from damage. As a result, the e-cigarette vapour destroyed nearly 85% of the cells.
