People are usually interested in how long nicotine remains in the system because their employer wants to test for nicotine—either as a condition of employment, or more commonly to determine the cost of health insurance. As unfair as it seems, employers and insurance companies don’t have to distinguish between cigarette smokers and users of nicotine in safer forms, like vaping or smokeless tobacco. Even the use of nicotine gum—which the fda approves for long-term use—can be treated as a health risk by employers, and lead to higher insurance prices for employees. Insurance companies consider the presence of nicotine a reliable indicator that the test subject is a tobacco user or a user of nicotine replacement therapy (nrt) products, which usually means an ex-smoker (and someone likely to return to smoking, as more than 90 percent of nrt users do).

Neither nicotine nor cotinine will be detectable in your urine after 3 to 4 days of stopping tobacco products. If you smoke menthol cigarettes or breathe in secondhand menthol smoke, cotinine may stay in your urine longer.
