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.
Because body systems are different from person to person, and nicotine is an addictive drug, it may take a longer or shorter time to process. The range is 48 to 72 hours depending on the amount of tobacco or NRT product you are using and how well your body is able to process the poison out of your system. Many companies are testing for signs of smoking before a new hire. They will take a urine sample and test for many drugs, including nicotine, before your actual start date. If the drug test comes back positive, they may consider not hiring you. There are several reasons for this.
