Letâs find out how long nicotine can be found in your body after the last time you use tobacco. In blood: When you smoke a cigarette, 1 mg of nicotine enters your blood. The nicotine will totally be gone within 1-3 days after your last using tobacco. In urine: The urine test normally can detect nicotine level within 3-4 days after the last time you use tobacco. However, if you often smoke or you are passive smokers, nicotine can stay for a period of 15 to 20 days in urine. After this period, no traces of toxic can be found in your urine.
Unfortunately, thereâs no clear-cut universal timeline to determine how quickly nicotine will be eliminated from your system. Since nicotine has a half life of approximately 2 hours, it theoretically should be cleared from your body within 11 hours. That said, not everyone will experience complete clearance of nicotine from their system within an 11 hour period.
