I have to take a blood-drawn cotinine test tomorrow for


Q: I have to take a blood-drawn cotinine test tomorrow for a hospital job. I haven't smoked a cigarette in 5 days (used to be 10 menthol cigs/day). Haven't been inhaling second hand smoke or anything like that. I normally drink alot of water on a daily basis. Do you think I'll pass the blood - drawn cotinine test? I'm 6 ft 250 lbs if that helps


A:   Thank you for writing to us.

You may test positive for the drug test as it takes up to 7 days to clear the cotinone from the urine and the blood. If a sample of hair was being tested, you will test positive for up to a month.

I recommend that you quit smoking as it is hazardous to both your health and people around you. Especially in a hospital.

All the best.
