The length of time that nicotine stays in the body and cotinine can be a reliable indicator of nicotine use depends on the amount of tobacco smoked, the number of years smoking tobacco, and the type of nicotine test performed. It can be as short as 2 days, or as long as 3 months.
However the byproducts of nicotine can be detected in the blood for up to a month after you stop smoking, depending on usage. This is only of concern if you are in a situation where someone else might want to test you for the presence of nicotine or nicotine byproducts in your system. Votes: +0. Comment Vote up Report.
