Most experts and healthcare professionals agree that nicotine is unquestionably the most addictive drug in use today. The principle source of nicotine is tobacco products. Tobacco smoking, vaping of liquids that contain nicotine or chewing of tobacco results in the absorption of nicotine through the lung and buccal/nasal epithelium, after which nicotine is metabolized into 20 different metabolites excreted in urine.
Cotinine, a major metabolite of nicotine, accumulates in the body with regular smoking. It is reported that Cotinine is stable in body fluids and has a relatively long half-life of approximately 17 hours. Therefore the detection of Cotinine is less dependent on the time of sampling than that of nicotine and other metabolites.
Cotinine has been widely used as a bio-marker of tobacco exposure. Methods of analysis for Cotinine in biological fluids include, gas chromatography mass spectrometry, HPLC, HPLC-mass spectrometry, EIA and RIA. These methods usually require special equipment and complicated operation procedures.
