Nicotine: “When someone stops using tobacco and nicotine products, it can take more than two weeks for the blood level of cotinine to drop to the level that a non-tobacco user would have and several weeks more for the urine level to decrease to a very low concentration.” REF: http://labtestsonline.org/understanding/analytes/nicotine/tab/test/

Probably one day whi: Probably one day, which is a guess (24 hrs.) it's half life is 2 hrs, and it is metabolized by the liver and excreted by the kidneys into the urine. In a heavy smoker there be a higher plasma nicotine concentration and it may take 2 days. This is an educated guess.
