A member asked:
When after quitting smoking does nicotine show up on blood test?
A doctor has provided 1 answer
2-4 days: The clearance rate for nicotine from blood is between two to four days. So, if you can refrain from smoking for a week prior to the test, it is unlikely that a medical screening test would be sensitive enough to detect that you were a smoker. If you are smoker havy smoker for long time it my take longer.
