Q: I do not smoke but all of my friends do. I have to take a blood and urine test on saturday for cotinine for my health insurance. I just read that cotinine can get in your system just from second hand smoke.

A: Cotinine has an in vivo half life of approximately 20 hours, and is typically detectable for several days to up to one week after the use of tobacco. The level of cotinine in the blood is proportionate to the amount of exposure to tobacco smoke, so it is a valuable indicator of tobacco smoke exposure, including secondary (passive) smoke. People who smoke menthol cigarettes may retain cotinine in the blood for a longer period because menthol can compete with cotinine enzymatic metabolism. Genetic encoding of liver enzymes may also play a role, as black people routinely register higher blood cotinine levels than white people. Several variable factors, such as menthol cigarette preference and puff size, suggest that the explanation for this difference may be more complex than gender or race.
