J Natl Cancer I:研究称过滤嘴香烟危害更大,薄荷香烟更危险

2017-05-25 中国循环杂志/文韬 中国循环杂志

美国一项研究发现,香烟的过滤嘴或可增加肺腺癌发生风险。根据研究结果,研究者建议美国疾控部门是否应考虑禁止香烟过滤嘴。研究者还称,薄荷香烟还允许更深入地吸入香烟烟雾,因为薄荷脑是一种麻醉剂。烟草商在上世纪60年代开始使用过滤嘴,同时吸入燃烧的烟草和空气。当时,这被认为是使香烟更安全。之前就有发现,由于烟草公司在过去50年间采取了一系列隐秘的手段,吸烟变得更加危险、更易上瘾。美国“无烟草青少年运动”组

美国一项研究发现,香烟的过滤嘴或可增加肺腺癌发生风险。根据研究结果,研究者建议美国疾控部门是否应考虑禁止香烟过滤嘴。

研究者还称,薄荷香烟还允许更深入地吸入香烟烟雾,因为薄荷脑是一种麻醉剂。

烟草商在上世纪60年代开始使用过滤嘴,同时吸入燃烧的烟草和空气。当时,这被认为是使香烟更安全。

之前就有发现,由于烟草公司在过去50年间采取了一系列隐秘的手段,吸烟变得更加危险、更易上瘾。

美国“无烟草青少年运动”组织的医生曾表示,现在的香烟比1964年的香烟致病风险更高。该组织发现,尽管吸烟数量下降了,但吸烟者患肺癌和慢性阻塞性肺病的风险要比1964年高许多。其原因在于,香烟产品设计和香烟的成分发生了改变。

美国肺协会高级科学顾问Norman H. Edelman博士称,自从卷烟公司开始制造和推广香烟过滤嘴后,肺癌的比例明显升高。今天,腺癌占所有肺癌的80%至85%左右。

研究称,使用香烟过滤嘴和腺癌之间的关系是非常强大的,因此“高度暗示”因果关系。

“过滤嘴香烟中较小的颗粒通过支气管进入称为细支气管的较小管,”作者称,因为这刺激了发现腺癌的肺周边组织。

研究者回顾了数百篇已发表的科学论文,包括人类研究,动物研究和吸烟机研究。研究发表在Journal of the National Cancer Institute上。
