Smoking and Tobacco
Nicotine in blood or urine
Can a nicotine test tell how long a person has stopped smoking? I am to be tobacco free for 2 months before I can have a procedure done...I will be tested...but not sure how. I was wondering if can tell I have been smoke free for that long.
A test for the breakdown product of nicotine is called cotinine (COAT-a-neen). This stays in the body longer than nicotine and is a good marker for long-term smoke exposure. This can be measured in blood, saliva, and urine. It would be best for you to follow the directions to not smoke for two months prior to a procedure being done as there are health concerns about smoking exposure.
