Nicotine: Nicotine will not be detected in a blood test after not smoking for 3-4 days. Cotinine is not detectable after 1-10 days. Neither will be detectable in urine tests after 4 days.

Probably not: “When someone stops using tobacco & nicotine products, it can take more than 2 weeks for the blood level of cotinine to drop to the level that a non-tobacco user would have & several weeks more for the urine level to decrease to a very low concentration.” REF: http://labtestsonline.org/understanding/analytes/nicotine/tab/test/
