To the Editor: Curbs on E-Cigarettes

To the Editor:

Re “Hot Debate Over E-Cigarettes as Path to Tobacco, or From It” (“The New Smoke” series, front page, Feb. 23):

As you note, the health effects of e-cigarette use remain unknown, and their use may actually be leading to greater smoking of traditional cigarettes, especially among children.

In fact, a recent study of 76,000 South Korean teenagers indicates that users of e-cigarettes were less likely to succeed in quitting smoking and were more likely to be heavy smokers.

The availability of e-cigarette flavored vapors (mango and watermelon) enhances the attraction. The troubling increase in the use of e-cigarettes among American teenagers found in the survey by the Centers for Disease Control and Prevention, also reported in the article, suggests that e-cigarettes are a gateway to tobacco addiction.

The American Thoracic Society, as a member of the Forum of International Respiratory Societies, supports an age restriction and government regulation of the sale of e-cigarettes, which in many states do not exist. Until more research is done, it is dangerous to promote their widespread use.
