In results presented at the 2002 annual meeting of the American Society for Reproductive Medicine,Cotinine, the primary breakdown product (metabolite) of nicotine, shows promise for improving memory and for protecting brain cells from diseases such as Alzheimer's and Parkinson's -- but perhaps with less addiction and other side effects of nicotine, report scientists from the Medical College of Georgia. Although cotinine (the metabolite of nicotine) is often detected in the urine of nonsmokers, the level of urinary cotinine can still be used to differentiate smokers from nonsmokers who have been exposed to secondhand tobacco smoke. D. A comparison of blood nicotine and cotinine levels in a group of snus users and a group of cigarette smokers on a day of normal snus use and smoking, showed that the snus users and cigarette smokers had roughly the same levels of nicotine (37 ng/ml) by the end of the day.
