Originally created with the intention of aiding adults in quitting traditional cigarettes, e-cigarettes have been finding their way into the hands of teenagers in recent years with an ever-increasing frequency. In 2011, less than five percent of teenagers reported using e-cigarettes; by 2018, that number had jumped to more than 37 percent. Despite being touted as a “safe” and even “healthy” alternative to traditional tar-and-chemical-laden cigarettes, most e-cigarettes still contain nicotine, which has long been known as an addictive substance. And that’s at the heart of the issue of teen e-cigarette use, says Nora D. Volkow, the director of the National Institute on Drug Abuse, “It is urgent that teens understand the possible effects of vaping on overall health, the development of the teen brain and the potential for addiction.”
