The decline in tobacco use among teenagers seen in recent years may have been short-lived as the popularity of e-cigarettes among young people increases.

Scientists from the University of Nebraska Medical Center noticed this trend while studying data from the 78,000 teens and young adults who participated in the National Youth Tobacco Survey between 2014 and 2017.

研究人员发表了他们的研究结果 贾马儿科 。

The prevalence of current use of all tobacco products in young people decreased from 17 percent in 2014 to less than 14 percent in 2017.

2014年使用调味烟草的高中生人数从2014年的69％下降到57％，但2017年该号码增加到63％。

Hunging Dai，Phd，Lead研究作者以及内布拉斯加州大学医疗中心公共卫生学院生物统计学系副教授，主要将上升率归因于调味的电子卷烟。

随着烟草和其他烟草产品的使用减少或平衡，调味的电子烟用途持续到2018年在高中生中升。

根据新的美国食品和药物管理局（FDA），2017年至2018年，电子卷烟用户的数量增加了150万学生 report 。

在这份报告中，31％的高中生，vape由于味道产品的可用性而表示，他们选择了电子烟。

“The perception that e-cigarettes are a safe alternative, along with many new products geared towards young people, is a big part of the rise,” said Dr. Steven Rowe, a professor in the Division of Pulmonary, Allergy, and Critical Care Medicine at the University of Alabama at Birmingham.

“This is alarming because it’s grown faster than expected, and the perception that it’s safe is clearly wrong,” he told Healthline.

Cigarette smoking is responsible for more than 6 million deaths around the world each year, according to the Centers for Disease Control and Prevention (CDC) 。其中包括每年480,000人死亡。

CDC还报告说，对于因吸烟而死亡的人，至少30人患有严重的吸烟有关的疾病。

The Office of the U.S. Surgeon General reports 如果吸烟以当期持续，每13百万名儿童每13名或每13个孩子中的560万，最终会从吸烟有关的疾病中死亡。

The FDA unveiled the largest coordinated enforcement effort in the agency’s history last summer. It issued more than 1,300 warning letters and fines to retailers that sold e-cigarette products, such as JUUL, to underage youth during a nationwide undercover operation.

The Surgeon General also released an咨询报告12月，在过去的一年中，在过去的一年中，在过去的一年中，在过去的一年里，在过去的一年中，他们的卷烟在“疫情的比例”中指出。

The press release indicated that high school students using e-cigarettes within the past 30 days had grown to more than 75 percent. There was an increase of almost 50 percent among middle school age students as well.

“我们需要保护我们的孩子免受所有烟草产品，包括所有形状和尺寸的电子烟，”外科医生将军副海军上将Jerome M.亚当斯在一份声明中表示。

“我们从未见过美国年轻人的任何物质的使用，因为电子烟用途，”美国卫生和人力服务部（HHS）秘书Alex Azar。

The FDA and the HHS agree that further research is needed to fully understand the effects of e-cigarettes.

The University of Rochester Medical Center and the Roswell Park Comprehensive Cancer Center has been awarded a $19 million grant funded by the National Cancer Institute to study the issue.

虽然许多人看着电子卷烟作为“安全的替代品”，但有些人 研究 shows that smoking during adolescence increases the risk of developing both cognitive impairment as well as potential psychiatric disorders later in life.

尼古丁可以影响负责记忆，学习，关注和大脑可塑性的大脑的区域。早期接触尼古丁可以具有长期影响。

“我们不能让香烟成为年轻美国人的尼古丁成瘾的卷烟，”亚萨尔说。

“Vapor with nicotine is highly addictive, and young people are especially at risk for addiction,” Dr. Rowe said. “Deciding to smoke is regretted by many people even a short time later, after addiction has already taken hold.”
