Big Drop in Vaping Among American Students
A U.S. government study has found that vaping rates among young students fell sharply this year. The drop comes after last year's sudden increase in vaping-related illnesses and deaths.
The national survey, released this week, showed that just under 20 percent of high school students said they were recent users of e-cigarettes and other vaping products. Just 5 percent of middle school students said they had recently used them.
That marks a big decrease from a similar survey in 2019. The earlier survey found nearly 28 percent of high school students and 11 percent of middle school students had recently vaped.
The 2020 survey was carried out by the Centers for Disease Control and Prevention (CDC) in partnership with the U.S. Food and Drug Administration (FDA).
About 20,000 American students took part in the survey from mid-January to mid-March. They were asked about the use of any vaping or tobacco products during the past month.
While the number of students smoking cigarettes has reached all-time lows in recent years, the use of vaping products has exploded. Officials say the vaping increase was linked to popular e-cigarettes, like those made by Juul Labs of San Francisco.
Earlier this year, the FDA barred some flavors from vaping devices mainly used by minors. And federal law now bans sales of all tobacco products and e-cigarettes to anyone under age 21.
Public health experts have wondered if last year's sudden increase in vaping related illnesses may have caused some students to give up vaping. Most of the cases happened in August and September. By year's end, more than 2,600 illnesses and close to 60 deaths had been reported.
Most of those who got sick said they had vaped mixtures containing THC. That is the substance in marijuana that produces a high. Health officials eventually centered their investigation on these THC products and on a chemical compound called vitamin E acetate, which had been added to some THC vaping liquids.
Matt Myers of the Campaign for Tobacco Free Kids said in a statement the survey showed a "meaningful drop" in teen vaping. But he criticized the Trump administration for not following through on a promise to ban all flavored e-cigarettes. The policy did not cover disposable e-cigarettes, which saw a big increase in this year's survey.
"As long as any flavored e-cigarettes are left on the market, kids will get their hands on them and we will not solve this crisis," Myers said.

美国学生吸电子烟人数大幅减少
美国政府的一项研究发现，今年青少年学生的电子烟吸烟率大幅下降。去年，吸电子烟导致的相关疾病和死亡人数骤然增加。
本周发布的全国调查显示，只有不到20%的高中生表示最近使用了电子烟和其他电子烟产品。只有5%的中学生称他们最近使用了电子烟。
与2019年的一项类似调查相比，这一数字大幅减少。此前调查发现，近28%的高中生和11%的初中生最近使用过电子烟。
2020年的调查由美国疾病控制预防中心（简称CDC）和美国食品药品监督管理局（简称FDA）联合进行。
这项调查在1月中旬至3月中旬进行，约2万名美国学生参与。他们被问及在过去一个月使用电子烟或烟草产品的情况。
虽然近年来吸烟学生人数达到了历史最低水平，但电子烟产品的使用却呈爆炸式增长。官员表示，电子烟的盛行与旧金山JUUL实验室等烟企推出的备受追捧的电子烟产品有关。
今年早些时候，美国食品药品监督管理局禁止了某些口味的电子烟产品，这些产品的用户主要是未成年人。现在，联邦法律禁止向21岁以下人群出售烟草产品和电子烟。
公共卫生专家想知道，去年电子烟相关疾病的激增是否会让一些学生放弃使用电子烟。大多数病例发生在8月和9月。截至去年末，美国累计报告了2600多例电子烟相关疾病，其中近60人死亡。
大多数患者表示，他们吸食了混合四氢大麻酚（简称THC）的电子烟。四氢大麻酚是大麻中令人兴奋的物质。卫生官员最终将调查重点集中在这些四氢大麻酚产品和一种名为维生素E醋酸盐的化合物上，这种化合物被添加到某些四氢大麻酚蒸气液中。
“无烟儿童运动”的马特·迈尔斯在声明中表示，调查显示青少年吸烟率“显著下降”。但他对特朗普政府未兑现禁止所有口味电子烟的承诺进行了指责。这项政策未涵盖一次性电子烟，这类电子烟的使用在今年的调查中大幅增加。
迈尔斯表示：“只要市场上还有风味电子烟，孩子们就能接触到它们，我们就无法解决这一危机。”
