While the number of U.S. college students smoking cigarettes has been increasing since 1993 to the current 33 percent, the use of e-cigarettes has been climbing since 2011.
A recent study led by Adam Goldstein, director of UNC Tobacco Intervention Programs, published results showing that adolescents with prior experience only with electronic cigarettes are more susceptible to future cigarette usage. It also shows there is a large population of adolescents from the study who have been identified as susceptible to e-cigarette usage but not traditional cigarette usage.
This finding is unsurprising, considering the public perception that e-cigarettes are acceptable tobacco substitutes, despite the 2016 Surgeon General’s report stating e-cigarette use among adolescents as a major public health concern.
Leah Ranney, associate director of the UNC's Tobacco Prevention and Evaluation Program, credited adolescent appeal to e-cigarettes to three main factors. The association of tobacco products by friends and family was the primary reason, but flavors are a close second, particularly concerning middle and high school students, as 73 percent of young adults use flavored tobacco products. The third reason, Ranney said, is the idea that e-cigarettes are less harmful, though that data concerning their health effects is not yet available.
Evidence for nicotine damage, however, is in. Nicotine causes harm to developing brains, which continue to grow until an individual’s early- to mid-20s. Furthermore, Ranney noted that e-cigarettes contain chemicals that are harmful to lungs.
