There was no statistically significant association between type of cigarette and serum cotinine level (P = 0.31), and a borderline association with self-reported use within the 5 days leading to specimen collection (P = 0.07). 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.
