JAMA Pediatr:电子烟让青少年更易吸烟上瘾

2014-03-11 佚名 不详

日前,美国加州大学旧金山分校的研究人员发现,对于青少年来说,被视为传统香烟替代品的电子烟不仅不能帮助他们戒烟,而且可能导致其更容易对尼古丁上瘾。研究人员呼吁,随着电子烟日益普及,有关部门应迅速制定监管措施。 研究人员在JAMA Pediatrics上报告称,他们调查了近 4 万名美国中学生和高中生,结果发现 2011 年约 3.1% 的美国青少年抽电子烟,但在 2012 年这一比例升至 6.5%

日前,美国加州大学旧金山分校的研究人员发现,对于青少年来说,被视为传统香烟替代品的电子烟不仅不能帮助他们戒烟,而且可能导致其更容易对尼古丁上瘾。研究人员呼吁,随着电子烟日益普及,有关部门应迅速制定监管措施。

研究人员在JAMA Pediatrics上报告称,他们调查了近 4 万名美国中学生和高中生,结果发现 2011 年约 3.1% 的美国青少年抽电子烟,但在 2012 年这一比例升至 6.5%。进一步的分析表明,抽电子烟的青少年更有可能吸传统香烟,更不容易戒掉烟瘾。

研究人员在论文中写道:“电子烟可能促使青少年对尼古丁上瘾,而不太可能让他们放弃吸传统香烟。”电子烟是一种非燃烧的烟类替代产品,其金属烟管内含有电池、尼古丁盒以及喷雾器。使用者可吸入蒸发的尼古丁并呼出白色雾气。根据个人喜好,烟管内可以加入巧克力或者薄荷等物质,以产生特殊口味。

过去几年,电子烟在世界各地迅速普及。美国的一些生产厂商们声称它们比传统香烟安全,有助于戒掉烟瘾,并且在电视、广播等媒体上像上世纪五六十年代推广传统香烟那样大做广告。许多公共卫生专家对此表示担忧。

论文资深作者、加州大学旧金山分校教授Stanton Glantz表示:“在我看来,大肆推广电子烟不仅在鼓励青少年吸电子烟,也促使青少年抽传统香烟。”《JAMA Pediatrics》配发的一篇社论说,尽管对电子烟的公共健康益处仍需进一步了解,但近年来电子烟的使用在青少年中快速增长“表明政策制定者需要迅速行动起来”。
