To estimate the prevalence of electronic cigarette use among teenagers and its connection with the consumption of tobacco.
In 2014 we conducted a survey of 3319 middle and high school students.
Among the students, 56% had tried an electronic cigarette at least once (boys: 59.9%, girls: 49.3%; ranging from 31.3% for the 8th grade students to 66.1% for the 12th grades). However, only 3.4% reported that they used electronic cigarettes every day. Initiation of e-cigarette use in these teenagers was principally due to use by friends or triggered by curiosity and they usually choose fruit or sweet flavours initially. The majority could not give the concentration of nicotine in e-cigarettes that they used. Moreover, 61.5% of the students had ever tried tobacco and 22.3% were daily smokers. Our study found a strong link between vaping and smoking. 80% of the students who had ever tried conventional cigarettes (94% for the daily smokers) had also tried an electronic cigarette, versus 16% of the student who have never smoked. Few students (6.2%) used electronic cigarettes without smoking tobacco too. Usually, they have tried tobacco before trying an electronic cigarette. Only tobacco smokers seem to smoke electronic cigarettes with nicotine.
Although our study shows that teenagers frequently try electronic cigarettes, it does not prove, for the moment, that vaping itself usually leads to nicotine addiction. However, as most of the teenagers are unable to tell if the electronic cigarette they are testing contains nicotine, it raises the possibility that they could be vulnerable to manipulation by the tobacco industry.
评估青少年中电子烟的使用流行率及其与烟草消费的关联。
2014年，我们对3319名中学生和高中生进行了一项调查。
在这些学生中，56%的人至少尝试过一次电子烟（男生：59.9%，女生：49.3%；八年级学生为31.3%，十二年级学生为66.1%）。然而，只有3.4%的人报告称他们每天使用电子烟。这些青少年开始使用电子烟主要是因为朋友使用或出于好奇，他们最初通常选择水果味或甜味。大多数人说不出他们所使用的电子烟中的尼古丁浓度。此外，61.5%的学生曾尝试过烟草，22.3%的学生是每日吸烟者。我们的研究发现吸电子烟和吸烟之间有紧密联系。80%曾经尝试过传统香烟的学生（每日吸烟者中这一比例为94%）也尝试过电子烟，而从未吸烟的学生中这一比例为16%。很少有学生（6.2%）在不吸烟的情况下使用电子烟。通常，他们在尝试电子烟之前已经尝试过烟草。似乎只有吸烟者会吸含尼古丁的电子烟。
尽管我们的研究表明青少年经常尝试电子烟，但目前并未证明吸电子烟本身通常会导致尼古丁成瘾。然而，由于大多数青少年无法判断他们所尝试的电子烟是否含有尼古丁，这增加了他们可能易受烟草行业操控的可能性。
