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.
Determining exactly how long nicotine is detectable in the body depends on many variables, including which kind drug test is being used. Nicotine - also known as cigars, cigarettes, smokeless tobacco, snuff, spit tobacco - can be detected for a shorter time with some tests, but can be visible for up to three months in other tests.
