US Health Report: E-Cigarettes Not Safe for Young People
The United States' top health official says electronic cigarettes can cause health problems for young people.
Surgeon General Vivek Murthy released his first report on e-cigarettes this week. He called the devices a public health threat to America's youth.
The surgeon general is the U.S. government's top medical officer. He uses scientific information to give the best advice for improving health and reducing the risk of sickness and injury.
Most electronic cigarettes use nicotine, a chemical found in tobacco plants, just like traditional cigarettes. But users do not light e-cigarettes because they are powered by a battery. They usually also contain flavoring and other chemicals.
E-cigarettes have increasingly grown in popularity nationwide since 2010. Officials say the devices are now the most used tobacco product by American youth and young adults.
In releasing the report, Surgeon General Murthy said the rising popularity of e-cigarettes is hurting past efforts to reduce tobacco use among young people.
"It also threatens 50 years of hard-fought progress that we have made curbing tobacco use. And it places a whole new generation at risk for addiction to nicotine..."
He also said the new report is meant to help families and communities understand the scientific reasons why e-cigarettes are harmful.
"The message from the report is clear. Nicotine-containing products in any form, including e-cigarettes, are not safe for youth."
The Surgeon General's report notes that nicotine is a highly addictive chemical. Users can develop a dependence on the drug.
The report says nicotine can harm brain development in teenagers and young adults. Murthy said those harmful effects can include deficits in attention and learning, reduced impulse control, and mood disorders.
The report notes research showing that young people who use e-cigarettes are more likely to use traditional cigarettes. It also found that chemicals sent into the air by e-cigarettes can harm the users and people around them.
Supporters of e-cigarette use have suggested that the devices can help smokers of traditional cigarettes cut back or even stop smoking. But Murthy said there is no evidence to back up this claim. He said millions more children are now being exposed to nicotine through e-cigarettes.
Murthy noted that he is keeping "an open mind" to see if future evidence proves that e-cigarettes can help adults stop smoking.
The report calls for restrictions on the amount of advertising used in e-cigarette ad campaigns. It also urges national educational programs to inform young people about the risks of the devices. The surgeon general said U.S. officials need to act now to help create a healthy, tobacco-free generation.
In a public service video message, Murthy gives a strong warning to parents. "You're kids are not an experiment. Protect them from e-cigarettes."

本周，卫生局局长维伟卡·默西（Vivek Murthy）发表了其第一份有关电子烟的报告 。他表示，电子烟已经威胁到美国年轻一代的公共健康 。
卫生局局长是美国卫生部门最高领导 。为了改善人类健康及降低患病的风险，他利用科学信息给出最佳建议 。
多数电子烟与传统香烟一样含有尼古丁，这是一种烟草植物特有的化学物质 。因为电子烟使用电池，因此无需人工点燃 。电子烟也含有香料及其他化学物质 。
2010年以来，电子烟开始在全国范围内流行起来 。官员称，目前美国的青少年和年轻人是电子烟的主要消费群体 。
“50多年来，在控制香烟消费量方面所取得的艰难进展也受到威胁 。此外，它还让年轻一代身陷尼古丁成瘾的危险 。”
报告中的信息一目了然 。一切含有尼古丁的产品，包括电子烟对于青少年来说都是有害的 。
报告还指出，尼古丁是一种高度成瘾性的化学物质 。容易让人对其产生依赖 。
报告显示，尼古丁会损害青少年和年轻人的大脑发育 。默西表示，具体表现包括主意力、学习能力下降、易冲动和情绪失控 。
报告称，研究表明吸电子烟的年轻人也可能会吸传统香烟 。电子烟释放的化学物质进入空气中也会对本人及周遭人群造成伤害 。
支持电子烟的人称，电子烟能减少人们吸烟传统香烟甚至戒烟 。而默西认为，目前没有任何证据支持这一说法 。他表示，因为电子烟数百万儿童面临着尼古丁的危害 。
该报告呼吁对电子烟的广告数量进行限制 。同时，还呼吁国家教育项目要普及电子烟对于年轻人的危害 。卫生局局长表示，美国政府需付诸实际行动来造就健康的无烟一代 。
在公益宣传的视频中，默西严厉地警告父母：“孩子不是实验品 。请保护他们远离电子烟 。”
