Abstract
The cigarette usually carries in its smoke significant doses of carcinogenic tobacco specific nitrosamines (TSNAs), which have been implicated as causes of oral, lung, oesophageal, and pancreatic cancer. However, there is substantial variation in nitrosamine content of the smoke of modern cigarettes. This variation is both unacceptable and unnecessary, as TSNAs can be readily removed during the manufacturing process. Removing a known carcinogen needs no justification, even though proof of benefit may not be forthcoming for decades.
摘要
香烟烟雾中通常含有大量致癌的烟草特有亚硝胺（TSNAs），这些物质被认为是导致口腔癌、肺癌、食道癌和胰腺癌的原因。然而，现代香烟烟雾中的亚硝胺含量存在很大差异。这种差异是不可接受且不必要的，因为亚硝胺在制造过程中很容易被去除。去除一种已知的致癌物无需理由，即使几十年内可能无法证明其益处。
