Urinary metabolites of nicotine, quantified as average percentage of total urinary nicotine [146] As nicotine enters the body, it is distributed quickly through the bloodstream and crosses the blood–brain barrier reaching the brain within 10–20 seconds after inhalation. [147] The elimination half-life of nicotine in the body is around two ...
Cotinine has an in vivo half-life of approximately 20 hours, and is typically detectable for several days (up to one week) after the use of tobacco. The level of cotinine in the blood, saliva, and urine is proportionate to the amount of exposure to tobacco smoke, so it is a valuable indicator of tobacco smoke exposure, including secondary (passive) smoke.

At least at "normal" levels, as nicotine in the human body is broken down, it has an approximate biological half-life of 1–2 hours. Cotinine is an active metabolite of nicotine that remains in the blood for 18–20 hours, making it easier to analyze due to its longer half-life. [33]
Products that help you quit smoking, like nicotine gum and nicotine patches, still leave traces of cotinine in your body. So, if you use these products, you’ll still probably be classified as a ...
