In addition to the unknown health effects, early evidence suggests that vaping might serve as an introductory product for preteens and teens who then go on to use other nicotine products, including cigarettes, which are known to cause disease and premature death. 2 More research is needed on the risks of this practice. Teens reported the following reasons for dripping: to create thicker vapor (63.5 percent), to improve flavors (38.7 percent), and to produce a stronger throat hit-a pleasurable feeling that the vapor creates when it causes the throat to contract (27.7 percent). Further, a study of high school students found that one in four teens reported using e-cigarettes for dripping, a practice in which people produce and inhale vapors by placing e-liquid drops directly onto heated atomizer coils. In addition, they are easy to hide from teachers and parents because they do not leave behind the stench of tobacco cigarettes, and are often disguised as flash drives. The easy availability of these devices, alluring advertisements, various e-liquid flavors, and the belief that they're safer than cigarettes have helped make them appealing to this age group. Some research shows that many teens do not even realize that vaping cartridges contain nicotine, and assume the pods contain only flavoring. Vaping devices are popular among teens and are now the most commonly used form of nicotine among youth in the United States. The person then inhales the resulting aerosol or vapor (called vaping). In many e-cigarettes, puffing activates the battery-powered heating device, which vaporizes the liquid in the cartridge. a mouthpiece that the person uses to inhale.a cartridge or reservoir or pod, which holds a liquid solution ( e-liquid or e-juice) containing varying amounts of nicotine, flavorings, and other chemicals.Most e-cigarettes consist of four different components, including: Some resemble pens, USB sticks, and other everyday items.
