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.
If you are getting nicotine from smoking a cigarette, you know that nicotine works quickly, so it does not last long in the bloodstream. Most of the nicotine is gone in a couple of hours, which is why most people need to smoke throughout the day to keep the nicotine levels up. It would pretty much be out of your system in 24-48 hours. One thing to note is that their are some rare people who do metabolize nicotine slowly, so just be aware that it can occur. The major breakdown product of nicotine is cotinine, which can be detected in urine. This byproduct lasts longer than nicotine, and can be found for up to one week after quiting smoking.
