How long does it take for nicotine to leave your body (urine and blood stream) after you've stop smoking?
It varies: Nicotine metabolism is complex. Most nicotine is metabolized in the body to co-nicotine, and this is what is tested for. Nictotine is 1/2 gone after 2 hours, co-nicotine about 20. It takes about 5 1/2 lives for a drug to be "97% gone". 10 half lives for 99.9% another source says a urine test can be positive 7 to 20 days after smoking. ...Read moreSee 1 more doctor answer
Stop smoking at 11:59pm on 03-04-16, I have a blood,urine and mouth test for nicotine. The test is between 3-14/18-2016 will i pass?
Yes, although...: Nicotine stays in urine and saliva for up to 4 days.

I am an overweight 40 yo female and have quit smoking . I am wondering after those 2 weeks will nicotine still be in my urine since my BMI is higher.?
Should be gone: The listed half life ( time until 1/2 is gone from your system) of nicotine is 2 hours in adults. 2 after stopping only 1/2 is left, then 1/4 and so forth. By two weeks out it is unlikely that any nicotine remains.

Im trying to quit smoking with patches is it the nicotine that constrics blood vessels or is it the other toxins in the smoke?
Nicotine constricts: While there might be a little cross-over, in general nicotine causes the vascular effects including constriction of blood vessels, & tars/other chemicals contribute carcinogens, promoting cancer. So in using the patch, you still get the effects of nicotine (hopefully at a lower dose than a cigarette) but are spared the hundreds of other chemicals. Go ahead & use the patches ... but get off ASAP! ...Read moreSee 1 more doctor answer
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! ...Read more
