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.
Nicotine can stay for 48 hours. Beyond this time it is not detected either in the blood or urine. However, the cotinine metabolite can leave traces for about 7 days. There are some people who have anomalies in their genes that trigger the slow metabolism of cotinine.
