Stopped Smoking. How Long Does Cotinine Stay In Blood System?
Question: how long does cotinine stay in your blood system. I have quit smoking and my company is now doing cotinine blood test for health insurance. We have our blood draw in 40 days should I be good to be considered a non smoker?
Hello.......
Thanks for your query. Cotinine does not stay in your blood system beyond 14-15 days considering the half life of cotinine that is 1.5 days. Hence 40 days is safe enough to pass the health insurance test.
