Report: E-cigarette use among teens may raise risk of smoking

January 29, 2018

By Michelle Manchir

Young people who use e-cigarettes are at an increased risk of using conventional cigarettes, and nicotine intake from e-cigarettes is comparable to conventional cigarettes, according to a report from the National Academies of Sciences, Engineering and Medicine released Jan. 23.

The report, available to download at no cost online, outlines "a comprehensive look at evidence on the human health effects of e-cigarettes," with researchers examining more than 800 peer-reviewed scientific studies, according to a news release about the report, which was commissioned by the U.S. Food and Drug Administration.

The evidence "suggests that while e-cigarettes are not without health risks, they are likely to be far less harmful than conventional cigarettes," the report says, noting, however, that e-cigarettes' "long-term health effects are not yet clear."

Other findings in the report include that, in addition to nicotine, most e-cigarettes contain and emit numerous potentially toxic substances; and that while the second-hand exposure to nicotine and particulate matter is less for e-cigarettes than regular cigarettes, use of e-cigarettes increases the particulate matter and nicotine in the indoor environment.

The ADA supports public policies to prevent tobacco use and urges its members to become fully informed about tobacco use prevention and cessation. The Association also aims to continue to educate and inform membership and the public about the health hazards attributed to the use of both traditional and nontraditional tobacco products, including e-cigarettes. (House of Delegates Resolution 78H-2016.)

In 2017, the ADA and the University of Texas MD Anderson Cancer Center launched a collaboration to focus on tobacco cessation and increasing HPV vaccinations for oropharyngeal cancer prevention.

Tobacco and tobacco cessation are topics covered by the ADA Science Institute on an Oral Health Topics page.

The ADA also offers a continuing education course, Tobacco Policy, Pharmacotherapy, and Dentistry, that includes information about training opportunities for dental health professionals who want to learn more about tobacco cessation pharmacotherapy.
