According to a team of scientists from the University of Rochester, vaping flavors such as vanilla and cinnamon are toxic to leukocytes, or white blood cells, increasing the risk of developing life-threatening diseases.
For the study, the researchers exposed immune cells to chemicals used in e-cigarette flavoring. They discovered that this type of cells produced substances responsible for inflammation and tissue damage. In addition, many of the flavoring chemicals caused a significant level of the death of these cells.
Senior author Dr. Irfan Rahman, of the environmental health sciences center, says: “While e-cigarettes are thought to have relatively less or no harm to the consumer’s health compared to tobacco smoke, vaping flavors are not safe for inhalation. Currently, these are not regulated, and alluring flavor names, such as candy, cake, cinnamon roll and mystery mix, attract young vapers.”
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.”
