How long will nicotine show up in an oral fluid test?

A doctor has provided 1 answer

Up to a week: depends on how much you smoke and the amount of nicotine in the cigarettes, to some extent. In general urine tests and blood tests for cotinine will show positives for 3-5 days, oral swabs potentially a little longer.
