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.
How long nicotine can be detected in your system also depends on how much of it has been converted to cotinine as cotinine has a longer half life. It takes 24 hours for cotinine in your system to be reduced by half.If you continue to smoke there will always be cotinine in your urine.icotine Half Life. Nicotine half life is about 2 hours. This means that 2 hours after you smoke a cigarette about half the nicotine has left your body and within about 2 hours after that the levels (from that last cigarette) are reduced by half again.
