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.
The first effects of nicotine withdrawal will be felt within 6 hours of having your last cigarette. However the peak time for these nicotine withdrawal side effects will be the second and third day post-smoking cessation. From then on depending on the factors I mentioned earlier on, nicotine withdrawal will begin to diminish over a 2 â 3 week period. So in effect, you could say on average that nicotine withdrawal will last about 3 weeks. However, it could be shorter in some people and in heavy smokers who have smoked for 20 years or longer, the nicotine withdrawal could last for up to 2 months. So you now have a rough idea of how long nicotine withdrawal does last. Most people will fall in between those withdrawal timelines.
