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.
While it may only persist in the body for 3-4 days after consuming tobacco products urine tests have been known to discover traces of nicotine for up to 15-20 days even with passive smokers. Blood tests: Nicotine can stay in the blood and is transformed into a metabolite called Cotinine which mixes in the blood affecting the body. Blood tests are generally more accurate in detecting this substance in the body and if there is even a hint of it in the body it can be found using this method. Hair test: A hair test conducted after a person has smoked for 1 month to 3 months regularly will show nicotine in their system for up to one year after they were smokers.
