Answer:
Vaping devices are popular among teens and are now the most commonly used form of nicotine among youth in the United States. Some research shows that many teens do not even realize that vaping cartridges contain nicotine, and assume the pods contain only flavoring. 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. 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. 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. 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).2 More research is needed on the risks of this practice.
hope this helps :)
