Nicotine Drug Test. In order to know the fact as to how long nicotine stays in your system, you need to remember the duration of smoking and the number of cigarettes smoked per day. Usually nicotine persists in the body for 2-4 days but in some cases it may also last for a few months. However, in the case of passive smoking the nicotine remains in the body for a long time. The presence of nicotine is usually detected in the urine, blood, and hair follicle through medical tests.
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.
