The use of electronic cigarettes or e-cigarettes has grown exponentially in recent years—especially among young adults in the United States.
The liquid used in e-cigarettes contains nicotine and other harmful chemicals, including heavy metals and carcinogens. The liquid nicotine used in e-cigarettes comes in thousands of different flavors, many of which are appealing—and harmful—to teenagers.
Researchers from the University of California, San Diego found that popular fruity vape flavors appear to contain the highest levels of cancer-causing materials. The study recommends that parents warn teens of the dangers associated with e-cigarettes to discourage usage.
