Figueiredo VC, Szklo M, Szklo AS, et al. Figure 1A shows the relationship between cigarettes per day and log-transformed plasma and urinary cotinine concentrations. Our studies would need additional data on puffing profiles to make more definitive conclusions on whether the association between time to first cigarette and cotinine could be attributed to more intense puffing behaviors, and whether symptoms of nicotine cravings are greater after waking.

I do workout about 3 to 4 days a week. An American Society for Pharmacology and Experimental Therapeutics study indicated that the half-life of cotinine was shorter in women than in men, which suggests that it clears more quickly in women. The mean level of plasma cotinine (397 294 (ng/ml)) and urinary cotinine (4490 3540(ug/mg creatinine)) was almost twice as high as that for smokers in the low dependent group.

Mucha L, Stephenson J, Morandi N, Dirani R. Meta-analysis of disease risk associated with smoking, by gender and intensity of smoking. Even if interventions successfully reduce cigarette consumption, concurrent reductions in biological exposure to tobacco smoke might depend upon nicotine dependence. In the Fourth National Report on Human Exposure to Environmental Chemicals (Fourth Report), CDC scientists measured cotinine in the serum (a clear part of blood) of 6,320 nonsmoking participants aged three years and older who took part in CDCs National Health and Nutrition Examination Survey (NHANES) during 20032004.
