Vaping these popular flavors may cause 'significant' health damage

Among the flavorings, those which mimic cinnamon and menthol appear the be the most harmful. The research conducted at Stanford University's School of Medicine gives key insights related to smoking of e-cigarettes. To further increase the accuracy of the study, the researchers chose to submerge the same type of cells in blood samples obtained from nonsmokers and people who smoke classic cigarettes.

"'The cells were less viable in culture, and they began to exhibit multiple symptoms of dysfunction". A number of people believe that e-cigarettes are less harmful as compared to normal cigarettes.

These endothelial cells then were exposed to six types of vapor from different e-liquids purchased online by the researchers.

In an effort to explore the potential dangers of e-cigarettes, the director of Stanford's Cardiovascular Institute, Dr. Joseph Wu, started digging. The cells are also less able to form new vascular tubes (that help in transporting fluids) and participate in wound healing.


The findings were published online May 27 in the Journal of the American College of Cardiology.

In the United States, cardiovascular disease is responsible for about one-third of smoking-associated deaths in smokers, and secondhand smoke causes approximately 34,000 early deaths from heart disease each year in nonsmokers. Although some studies have suggested that e-cigarettes deliver lower levels of carcinogens to users than do conventional cigarettes - perhaps decreasing the risk of cancer - the effect of e-cigarette use on vascular health has been unclear.

Use of e-cigarettes has skyrocketed since their introduction a decade ago.

Exposure to cinnamon and menthol e-liquids proved particularly damaging to cells, the researchers reported. Cinnamon, caramel, and vanilla flavors were found to boost the uptake of LDL and lipids, while caramel and vanilla also potentially negatively impacted new blood vessel growth. Although the ill effects of vaping aren't apparent in full, e-cigarettes lack numerous carcinogens present in treated tobacco.


Most people tend to believe that electronic cigarettes (also known as e-cigarettes) aren't as risky as regular ones. The result showed that the levels of nicotine in the blood serum between both groups were similar.

The U.S. Surgeon General has more about the health effects of e-cigarettes.

Wu further said that it is very important for e-cigarettes users to realize that the chemicals present in the e-cigarettes are circulating within their body and can affect their cardiovascular health.
