Cotinine

The human body converts nicotine from tobacco into cotinine. Drug tests can detect cotinine in the body after nicotine has disappeared. This makes cotinine tests effective to check if a person has smoked or been around smokers. Doctors, insurance companies, and employers use these tests to learn about someone’s tobacco use.
