关于电子香烟（e-Cigarettes），美国食品药品管理局（FDA）的态度是“电子香烟中的一些成份对人体同样有害或有毒，另一些成份则不安全。另外，电子香烟还可能诱惑年青人尝试其它烟草产品。由于关于电子香烟之临床研究资料仍未上交FDA，故FDA目前仍不能够为公众提供有关电子香烟之安全和有效的详尽资讯或评价”。更多资讯，请参阅http://www.fda.gov/NewsEvents/PublicHealthFocus/ucm172906.htm。

e-Cigarettes may contain ingredients that are known to be toxic to humans, and may contain other ingredients that may not be safe. Additionally, these products may be attractive to young people and may lead kids to try other tobacco products, including conventional cigarettes, which are known to cause disease and lead to premature death.

Because clinical studies about the safety and efficacy of these products have not been submitted to FDA, consumers currently have no way of knowing

whether e-cigarettes are safe for their intended use,

what types or concentrations of potentially harmful chemicals are found in these products, or　how much nicotine they are inhaling when they use these products.
