For heavy smokers, it might take a week (and possibly longer) for the cotinine traces to leave your urine or remain so small that they are undetectable.
Cotinine is what nicotine becomes when it is metabolized in the body. If this is the case, it can take 1-10 days. Urine Nicotine Test and Saliva Test.
