Nicotine addiction and withdrawal are intense and harmful on their own. One of the first additional health risks associated with vaping is bronchiolitis obliterans, a severe and irreversible lung disease often known as “Popcorn Lung.” This results from diacetyl, a common ingredient in flavored vape juice. This disease damages the tiny air sacs in your lungs and causes scarring and a narrowing of the airways. Other individuals have reported burn injuries from exploding, overheating, or otherwise malfunctioning vaping products. Most recently, the CDC has reported almost 200 cases of a new type of lung disease that has yet to be named but is believed to be related to vaping. This harmful lung problem causes difficulty breathing, chest pain, severe cough, vomiting, and fever. According to the National Institute on Drug Abuse (NIDA), 30.7% of e-cig users started smoking regular cigarettes within six months of starting. An August 2019 CDC study found that 38% of high school students have tried vaping, meaning more than one-third of all underage minors are exposed to the many health risks and addiction potential of vaping. A 2015 study by the U.S. Department of Health and Human Services found that over 50% of both middle schoolers and high schoolers were exposed to retail ads for vaping products. Since 2015, Juul Labs and other e-cigarette companies have been recorded as promoting internet advertisements on Facebook groups and websites specifically targeted at young people.
