One of the worst things you can do for your lungs and your overall health is to smoke. But many still don’t know that vaping is also dangerous. While experts expressed concern from the start, not everyone got the message. What Is Vaping? Vaping devices, or electronic-cigarettes (e-cigarettes), are battery-operated devices that people use to inhale an aerosol (vapor) that usually contains nicotine, flavorings and other chemicals. They can resemble traditional tobacco cigarettes, cigars or pipes. But many look like everyday things like pens or USB memory sticks. Whether they look like cigarettes, pipes or pens, they all use a vapor to deliver nicotine without tobacco. This vapor sparked the use of the term “vape” and “vaping” instead of smoking. Some may think vaping is better than smoking. Many people, especially teens and young adults, still think e-cigs are cool and a healthier choice than tobacco. In fact, e-cigarette use among young people has reached epidemic levels, says the American Lung Association’s advice to parents . E-cigarettes are the most commonly used tobacco products among young people and have been for years now. Many teens and adults don't realize how much they’re harming their lungs and their brains by using them. Is Vaping Healthier Than Smoking? E-cigarettes generally contain fewer toxic chemicals than the mix of 7,000 chemicals in smoke from regular cigarettes. But vaping is not healthy . Most e-cigarettes also contain many toxic chemicals and metals, including lead and formaldehyde. They can be very harmful, especially for young people and pregnant women. And most vape devices, as many as 99 percent of those sold in the U.S. , contain nicotine. Nicotine is as addictive as cocaine and heroin. In fact, one vaping dose can have as much nicotine as 20 regular cigarettes. The evidence is building about just how many ways vaping can damage your body. Even in a short time, vaping can damage your heart and lungs. It puts you at risk for: Cancer Lung disease Pneumonia Heart failure Chronic obstructive pulmonary disease (COPD) And research continues to show health risks from e-cigarette use. One recent study found a significant tie between former or current e-cigarette use and the development of respiratory diseases, including COPD, chronic bronchitis, emphysema and asthma, within two years of use. Vaping has also been linked to serious lung injuries, like bronchiolitis obliterans, often called popcorn lung . This condition happens when the smallest airways in your lungs are damaged by breathing in harmful chemicals, making it harder to breathe. Research has also found that exposure to secondhand vapor can be dangerous for others. Can Vaping Help You Stop Smoking? Researchers have gotten mixed results on whether vaping actually helps people stop smoking, compared to other methods for quitting. But what is clear is that most e-cigarettes are more harmful than the other methods for quitting. And most adults who use vaping to try to stop smoking do not stop smoking . Vaping can actually make it harder to stop. Studies show that vaping is just as addictive as smoking regular cigarettes. And about 28 percent of smokers who use vaping are less likely to quit, says the American Heart Association. Many end up smoking and vaping. Remember, no tobacco or vaping products are safe, says the Food and Drug Administration . So those who don’t use them should not start. And those who do should stop.
