导读:随着高科技的发展，各种电子产品已进入人们的现代生活，但它决非是一片净土。有的生产、经营和销售者所制销的“电子烟”，给青少年一代的教育带来了极大的挑战。
E-cigarettes, widely promoted as an alternative to smoking, are actually attracting young people who might not otherwise have smoked tobacco products, a new U.S. study suggested Monday.
星期一，美国一项新的调查研究显示，电子烟作为戒烟者吸烟的替代品，在社会上被广泛推崇使用，但实际上，电子烟的出现却大大吸引了那些不抽烟的青少年的注意。
E-cigarettes are thought by some to be responsible for a decline in American youth cigarette smoking, but researchers from the University of California, San Francisco (UCSF) indicated the reality is the opposite.
在美国，大家认为是电子烟的使用降低了青少年的吸烟率，但美国旧金山加利福尼亚大学的研究者发现，事实恰好相反。
The USCF researchers concluded that many kids who went on to smoke regular cigarettes may not have used nicotine at all if e-cigarettes did not exist.
研究者们表示，电子烟的出现让那些平时只抽普通香烟的孩子开始接触尼古丁。
"We didn’t find any evidence that e-cigarettes are causing youth smoking to decline," said lead author Lauren Dutra of the UCSF.
加利福尼亚大学该项研究的主要负责人Lauren Dutra 说“目前我们还未找到任何可以证明改抽电子烟能降低青少年吸烟率的证据。”
" some of the kids using e-cigarettes were also smoking cigarettes, we found that kids who were at low risk of starting nicotine with cigarettes were using e-cigarettes," Dutra said. "Recent declines in youth smoking are likely due to tobacco control efforts, not to e-cigarettes."
“一些孩子在使用电子烟的同时也在抽烟，我们发现那些接触尼古丁香烟可能性较小的孩子也在抽电子烟”，Dutra还说“近期青少年吸烟率的下降很可能是由于禁烟力度的加强，而非电子烟的功劳”。
For the study, researchers examined data from more than 140,000 middle and high school students who completed a U.S. government tobacco survey between 2004 and 2014.
为了这项研究，研究人员还专门调出了2004年至2014年接受美国政府抽烟调查的约140,000名初高中生的调查数据。
They found that cigarette smoking among U.S. adolescents declined during that decade, but did not decline faster after the advent of e-cigarettes in the U.S. between 2007 and 2009.
他们发现，在这十年内抽烟的青少年数量在下降，但在2007年至2009年期间，由于电子烟的出现，下降的速度开始变慢。
In fact, combined e-cigarette and cigarette use among adolescents in 2014 was higher than total cigarette use in 2009, according to the study.
事实上，据研究发现，2014年同时在抽烟和抽电子烟的青少年数量比2009年显示的抽烟数据更高。
E-cigarettes are battery-powered devices that look like cigarettes and deliver an aerosol of nicotine and other chemicals.
电子烟是带电池的电子香烟，看起来就像是真的香烟一样，通过雾化等手段，将尼古丁或者其他化学物质等变成蒸汽。
In August 2016, the U.S. Food and Drug Administration restricted e-cigarette purchases to adults ages 18 and older.
2016年8月，美国食品与药物管理局已经禁止18岁及以上的成人购买电子烟。
The FDA will also require a warning label on e-cigarettes, starting August 2018, regarding the addictive nature of nicotine.
考虑到尼古丁的成瘾性，从2018年开始FDA也将在电子烟上贴上警示标识。
