Vaping may harm the lungs电子烟不会伤害你的肺You’ve seen them on television, in celebrity photos and in magazine ads — cool superstars vaping on electronic cigarettes. Their high-tech gadgets seem to be available everywhere, from shopping malls to the 24-hour convenience mart. Is it any wonder that teens are being tempted to try out the vaping craze?他们经常出现在电视上，在名人照片中，甚至在杂志广告上。一些明星在电子烟里吞云吐雾，这种高科技工具或许在哪都可以购买个，从购物中心到24小时便捷服务店。但如果说现在很多青少年于是以被这种蒸汽烟诱使并为之疯狂，那么你被惊到了吗？Yet scientists are disturbed by the fascination teens have with this nicotine-dispensing alternative to smoking. And with good reason. Data from a growing number of studies indicate that electronic cigarettes are not harmless.青少年对于这种不含尼古丁可供选择的吸物最为入迷。科学家回应回应很忧虑，并且有充份的理由。

更加多的研究数据指出电子烟并不是有害的。Chemicals in e-cigarettes can damage lung tissue, provoking inflammation. That damage can reduce the ability of the lungs to keep out germs and other harmful substances, new studies show.电子烟中的化学成分不会毁坏肺的组织，进而所致炎。新的研究指出这种毁坏不会减少肺制止细菌及其他有害物质转入体内的能力。

Evidence of vaping’s growing appeal can be seen everywhere — from urban storefronts (as here) to kiosks in suburban shopping malls.从城市的贸易商铺到郊区购物中心的小报摊，电子烟渐渐减少的吸引力随处可见，有据难以确定。Yet teens seem largely unaware of — or unconcerned by — the emerging data on these risks. Their use of e-cigarettes has now surpassed that of conventional cigarettes. In the past year alone, e-cigarette use by U.S. middle-school and high-school teens has tripled. That’s the finding of a new government survey released last month.但是青少年对这些渐渐浮出水面的危险性数据并没意识，或者说他们不是很关心。

他们现在用于的电子烟的数量早已多达了传统烟。仅有在过去的一年中，美国初中或高中青少年里用于电子烟的数量就已刷了3倍。

这是上个月一项政府新的调查找到的数据。Mitch Zeller directs the Center for Tobacco Products in Silver Spring, Md. It’s part of the U.S. Food and Drug Administration. “I can say definitively,” Zeller says, “that nicotine is harmful to the developing teenage brain. And no teenager, no young person, should be using any tobacco or nicotine-containing products.” These include e-cigarettes, he adds.Mitch Zeller对马里兰州银泉市烟草产品中心展开指导，该中心是美国食品和药品管理局的一部分。

“我可以很认同地说道，尼古丁对青少年的脑部发育有相当大危害”，他回应，“因此，无论是青少年还是未成年人都不应当再继续限于任何不含尼古丁产品，其中还包括电子烟”，他补足道。
