Vaping probably started as a way to stop smoking but do you find yourself addicted to it now? Since there's no tobacco, these newfangled e-cigs are totally safe, right? Not exactly. The new way of lighting up may still do serious harm to your body, experts warn. (FYI: "Vaping" is the same as smoking an e-cigarette. Electronic cigarettes can also be called “e-hookahs,” “mods,” “vape pens,” “vapes,” “tank systems,” and “electronic nicotine delivery systems," or ENDS.)
Instead of inhaling smoke as with regular cigarettes, users of e-cigarettes inhale vaporised liquid (or aerosol) made up of a mixture of water and nicotine as well as other substances sometimes added for flavour and texture. There are now more than 7,000 different electronic cigarette liquid flavors, says Dr. Holly Middlekauff, a cardiologist at UCLA Health and researcher who's published several papers on the effects of electronic cigarettes.
Here's why e-cigarettes aren't great for you:
Inhaling vapor isn’t a great idea
Ingredients aside, inhaling the chemically induced vapor may cause problems. A University of Athens study found that “vaping” caused an increase in airway resistance. It’s a sign that your body is having a harder time breathing in smokers and non-smokers with healthy lungs, and at levels rivaling those of traditional cigarettes. Dr. Christina Gratziou, an author of the study, said that the evidence strongly suggests e-cigarettes can cause immediate harm after smoking them. Other research shows that e-cig use is linked to a higher risk of bladder cancer and the presence of carcinogens in e-cig users’ urine.
