Nevertheless, this does not stop the authors from drawing a conclusion. They conclude, despite their acknowledged inability to draw such a conclusion, that: "e-cigarette use is aggravating rather than ameliorating the tobacco epidemic among youths."

Wimmer implies that electronic cigarettes contain tobacco, arguing that: "There is no safe form of tobacco. Right now, the public health and medical community or consumers have no way of knowing what chemicals are contained in an e-cigarette or what the short and long term health implications might be."

For this reason, the FDA should think long and hard before jumping into a decision to ban the flavors in electronic cigarettes. It is possible that despite encouraging experimentation among some nonsmoking youth, flavored electronic cigarettes may actually have a net positive effect on the public's health by serving as an overall deterrent to youth smoking.

The policy also states: "We give your information to the people and companies that help us provide, understand and improve the services we offer.
