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.
Each portion of the body drains of nicotine at different rates. So while nicotine may be expelled from the blood in as little as a day after a person quits smoking, it may take as long as 15 or 20 days for it to be expelled from the urine. Once again, these times will vary depending on a variety of factors, most of which have to do with how long a person has been smoking.
