I had quit smoking, i smoked 10 cigs in 1 day. can i pass a nicotine/metabolite blood test 4 days later?

You should: Am not aware of people preferring blood tests to urine tests for cotinine, particularly since it can be found in blood only for a few hours after smoking, while it persists in urine for several days. In any case, testing should be negative 4 days later. More important than passing the test is actually quitting smoking, and taking care of your health. Please quit and stay quit!

Long term use?: “When someone stops using tobacco and nicotine products, it can take more than two weeks for the blood level of cotinine to drop to the level that a non-tobacco user would have and several weeks more for the urine level to decrease to a very low concentration.” REF: http://labtestsonline.org/understanding/analytes/nicotine/tab/test/
