After having done my medical a few days ago, I just read somewhere that smoking the morning before the medical exam is not recommended. I remembered having 2 cigarettes that morning, had one 4-5 hours before the exam and one more maybe an hour before the med. How does smoking affect the medical test (I am guessing that it might interfere with the urine testing?). How much nicotine in my system would screw up the results?
