Cotinine is a metabolite (byproduct) of nicotine as it is "processed" by the human body.
Cotinine is an indicator that nicotine has been inhaled or otherwise introduced into the body.
Cotinine levels <10 ng/mL are considered to be consistent with no active smoking.
Values of 10 ng/mL to 100 ng/mL are associated with light smoking or moderate passive exposure, and levels above 300 ng/mL are seen in heavy smokers - more than 20 cigarettes a day.
In urine, values between 11 ng/mL and 30 ng/mL may be associated with light smoking or passive exposure, and levels in active smokers typically reach 500 ng/mL or more.
Nicotine is rapidly metabolized and has a short half-life, but cotinine is metabolized and eliminated at a much lower rate. Because of the resulting increase with time in the cotinine to nicotine ratio in the body, including in the brain, it is of interest to examine the effect of cotinine on nicotine-induced changes.
