I am having an abdominal surgery on December 3rd. The day of my surgery I will be blood tested to see if I have quit smoking. I have been told they check nicotine and cotinine levels in your blood. Does anyone know how long I have to not smoke in order to pass this test? They told me 21 days, but I was wondering if it's a strict 21 days or are there any other ways to pass this test? Any information will be greatly appreciated!!!
