E-cigarette Flavors Can Cause Cardiovascular Disease

What is E-cigarettes?

Electronic cigarette is a handheld electronic device that simulates the experience of smoking a cigarette. E-liquid or juice are names for the flavoured solution that goes inside the e-cigarettes. It works by heating e-liquid which generates an aerosol or vapour that is inhaled by the user. Using e-cigarettes is commonly referred as “vaping”. The modern e-cigarette was invented in 2003 by Chinese pharmacist Hon Lik.

Health Risk

Till now health risks of e-cigarettes were uncertain and considered safer than traditional cigarettes but according to new study published in the Journal of ”The American College of Cardiology” the e-cigarettes can cause risk of heart diseases.

The liquid in the electronic cigarette is usually made of nicotine, propylene glycol, glycerine and flavorings. Some of the flavours are vanilla, fruit, sweet butterscotch, menthol, caramel, cinnamon and sweet tobacco.

For a reaction to vaping, Dr Joseph Wu (Director of Stanford University’s cardiovascular institute) said that “it’s not possible for me to go into a patient and strip their artery and test it”. So Dr Joseph Wu team grew the endothelial cells which line the interior of blood vessels (it support heart and cardiovascular health) and exposed them to different flavourings of e-cigarettes, to be confirmed about the actual cause of harmful effects: Nicotine or the flavours?

The team found out that some flavorings even in the absence of nicotine is able of triggering dysfunction in blood vessels, ultimately this dysfunction leads to increase in the risk of heart diseases. Among all the flavor mentioned above, menthol and cinnamon appears to be more hazardous for health. Cinnamon & menthol flavored e-liquids can disrupt the ability to form capillary like structures, which influences the growth of new blood vessels.

Wu said,"It is important for e-cigarette users to realize that these chemicals are circulating within their bodies and affecting their vascular health”.
