E-Cigarettes pose more harm than good as a tool to reduce smoking. Electronic cigarettes (e-cigarettes) only marginally increase the number of adult smokers who quit smoking, yet they inspire teens and young adults to progress to cigarettes-which may translate to more than 1.5 million years of life lost, according to a study published in the March 14 PLOS One. Since the1990s, tobacco control programs have reduced teen smoking, but e-cigarettes could slow or reverse those gains. Effective national, state, and local programs are needed to stop teens and young adults from using e-cigarettes, the authors concluded.
