If i stop smoking 4 days ago and take a nicoten urin test on feb 8 th can i pass the test for my job ?

Yes, it's likely: Depends to some extent on how heavy a smoker you were, and to some extent on your body build, but in general, cotinine should no longer be present about a week after stopping smoking, and usually even sooner. Please try to stay quit!

Testing: “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/
