How long will the nicotine stay in my blood or urine?
Trace amounts of nicotine can be detected in blood and urine for several hours, but they should be gone by 48 hours. However, if you are being tested for nicotine, there is a metabolite of nicotine, called cotinine, which can be detected in blood or urine for as long as 7 to 10 days after your last exposure to nicotine.
