How long does it take for cotinine to leave blood and urine after you quit smoking?

Cotinine test: This will depend on which test they are using so ask the tester. Do no chew or dip as this will show up as well.

Cotinine: “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/
