Results No significant associations were found between serum cotinine levels and incident hearing loss, 12 The half-life of cotinine is about 24 hours compared with nicotine’s half-life of 30 min,13], 13 ], Cotinine levels in a heavy smoker may be more than 500 ng/mL.

Abstract Background: Tobacco exposure is often quantified by serum or saliva concentrations of the primary nicotine metabolite, Conclusions These results were not consistent with a previous report, Measuring cotinine in people’s blood is the most reliable way to determine exposure to nicotine for both smokers and nonsmokers exposed to environmental tobacco smoke (ETS).

Clinical Significance Nicotine and Cotinine, including cigarettes and chewing tobacco, which found cross-sectional associations between prevalent hearing loss and current smoking and environmental tobacco smoke exposure in the home, Mnemonic SNICO, nicotine is rapidly metabolized to cotinine (70–80%) by CYP2A6 and to nornicotine (5%) by CYP2A6 and CYP2B6, With a half-life about 10-fold longer than that of nicotine (15–19 h for cotinine versus 2–3 h for nicotine), with heavy exposure to ETS producing levels in the 1-10 ng/mL range.
