原標題:E-cigs continue to spark debate over health risks/benefits

(HealthDay)—With sales of electronic cigarettes skyrocketing, Americans remain divided on whether the devices are a boon or a threat to public health.


That's the main finding of a new HealthDay/Harris Poll that surveyed over 2,000 adults on their e-cigarette views.


Vaping has long been promoted as a way to help smokers kick the habit—offering them a route to get nicotine without the carcinogens in tobacco smoke.


But e-cigarettes aren't harmless, according to the U.S. Centers for Disease Control and Prevention (CDC) and other health authorities. There's particular concern about young people vaping—in part, because nicotine can harm brain development, which continues until about age 25.

但美國疾控中心(CDC)和其他健康權威機構認為電子煙并非100%安全。 他們尤其關切蒸汽電子煙對青年人的影響,因為尼古丁會對大腦發育造成不良影響,而大腦完全發育大概在25歲左右。

In the poll, most adults did have misgivings about e-cigarettes: 85 percent said they were worried that the long-term health effects of the devices are unknown; and 83 percent were at least "somewhat" concerned about teenagers using e-cigarettes.

在這項民調中,大部分成年人對電子煙確實心存顧忌。 85%的人稱電子煙對健康的長期影響還不得而知;另有83%表示了對青少年使用電子煙的擔憂。

In fact, 43 percent of adults felt that e-cigarettes are actually more dangerous than traditional cigarettes.


On the flip side, about as many people (41 percent) viewed e-cigarettes as "healthier" than traditional cigarettes. And 42 percent rated them as an "excellent way" to quit.

反過來講,約有41%的人認為電子煙比傳統卷煙更安全健康。 42%的人甚至將它評為戒斷煙癮的“最佳方式”。

It all adds up to differing views, and possibly confusion, about e-cigarettes and their health effects.


There are, in fact, many unknowns.


Unfortunately, at this time we have no scientific evidence on the long-term health effects of e-cigarettes, especially given the unknown effects of the aerosols and flavorings in e-cigarette liquids, said Dr. Thanh-Huyen Vu, a research assistant professor at Northwestern University in Chicago.

芝加哥西北大學研究助理教授于青玄(Thanh-Huyen Vu)博士稱:“很遺憾,我們還未掌握到科學的證據以驗證電子煙對健康的長期影響,尤其是煙油中氣霧和香料對健康的影響。”

However, researchers know plenty about nicotine.


The drug "is well known to be addictive and toxic, and to have adverse effects on the cardiovascular system and on health in general," Vu said.


And that's enough to raise concerns about teenagers' e-cigarette use, she added.


In addition, Vu said, studies have found that teenagers and young adults who use e-cigarettes are more likely than non-users to take up smoking.


And what about adults who use e-cigarettes in place of traditional ones?


The devices do allow people to avoid the chemicals they would inhale from burning tobacco, Vu noted.


It's been speculated that using them may be associated with better health outcomes, compared to traditional cigarette smoking, she said.


But again, Vu pointed out, there's the nicotine and its own health effects.


E-cigarettes come in different forms, with some emulating traditional cigarettes or pipes. One highly popular brand, called Juul, is shaped like a USB flash drive, and reportedly accounts for one-third of e-cigarette sales in the United States.

電子煙形狀各異,有些似傳統香煙,有些似煙斗;其中 Juul是最受歡迎的一個牌子,外形類似USB,據報道它的銷量占美國電子煙市場的三分之一。

Last week, the CDC reported that Juul sales shot up 641 percent between 2016 and 2017. Researchers called the trend worrying because the devices have a particularly high nicotine content and are popular with young people.


No teenager should be vaping, said Gregory Conley, president of the American Vaping Association—referring to a common term for e-cigarette use.

美國蒸汽煙協會(American Vaping Association)會長格雷戈里·康利(Gregory Conley)認為青少年就不應該使用蒸汽電子煙。

However, Conley disputed the notion that e-cigarettes are driving kids to smoke. As researchers from the University of Buffalo recently argued, teen smoking has continued to decline at the same time e-cigarette use has risen.

然而,康利并不認為電子煙和青少年兒童吸煙有必然聯系。 最近,布法羅分校的研究人員辯稱電子煙的引入反而使青少年煙民數量降低了。

Conley questioned the poll finding that 43 percent of people think e-cigarettes are more dangerous than traditional cigarettes. He said past surveys have found less fear around the devices.

同時,康利也對“43%的人認為電子煙比傳統卷煙更危險”這一民調結論持質疑態度。 他說過去的所有調查都指向電子煙危害小。

But if people do think vaping is worse than smoking, Conley blamed misleading messages from certain researchers and media stories.


As long as vaping is helping smokers quit, it will bring public health benefits, he said.


Conley pointed to research evidence of that: Last year, a study at Georgetown University estimated that up to 6.6 million smokers would live "substantially longer" if they replaced their traditional cigarettes with e-cigarettes.


And a 2016 report from the Royal College of Physicians concluded that e-cigarettes—when used by smokers aiming to quit—are "likely" to benefit public health.

英國皇家內科醫學會(Royal College of Physicians)2016年的一份報告指出如果那些決心戒斷煙癮的煙民使用電子煙,則很可能給公共健康帶來巨大的效益。

Still, Vu said that based on studies so far, it's unclear how effective the devices really are in helping smokers ultimately quit. "E-cigarette use is still new, so it will take time to prove," she added.

然后,于博士說基于目前的研究,電子煙對戒斷煙癮的效用還不明確。 “電子煙仍是新興事物,需要時間去驗證它的長期效益。”

This HealthDay/Harris Poll was conducted online within the United States between Sept. 25-27 2018, among 2,008 U.S. adults (aged 18 and over). This online survey is not based on a probability sample and therefore no estimate of theoretical sampling error can be calculated.

這項民調于2018年9月25至27號采用在線調查的形式進行,參與調查的人數達2008人(年齡大于18歲)。 這項在線調查并非基于概率抽樣,因此理論上不存在抽樣誤差。
