菸草多長時間保持在你的血液中的人壽保險？
 Tobacco in the blood is indicated by a metabolite of nicotine called cotinine. Cotinine can be detected in a life insurance blood test for several weeks after smoking a cigarette, chewing nicotine gum, using chewing tobacco, etc. The test for cotinine is also sensitive enough that it nearly always detects actual tobacco use, rather than second hand smoke.
