How long after smoking will nicotine stay in your body and show up on a urine drug test?

Not In Drug Screen. Nicotine is not typically screened for in urine drug tests. Usually, you will see such things as narcotics, barbiturates, benzodiazepines, illegal substances but not nicotine. If being tested specifically for nicotine is a special test where it can be detected up to 4 days.
Weeks. Nicotine is metabolized relatively quickly, but one of the substances it is converted into hangs around longer. You will remain positive for at least two weeks after smoking cessation.
