How long does it take for nicotine to get out of your blood stream?

Question

I have to take a blood test on Friday and I Smoked 3 cigs Sat. Night. Will I fail the test? Thanks!!

Answer 1

If they are using the cotinine test, the half-life is about 18-20 hours, so you should be okay.

"Studies have shown that nicotine and cotinine are present in both active and passive smokers alike. Nicotine (Figure 1) is a
natural product of tobacco, and it is present in the body with a half-life of 1–2 hours. Cotinine (Figure 2), on the other hand, is a
metabolite of nicotine with a half-life of 18–20 hours."

Also:

"While nicotine will usually clear your system within a day, the byproducts of smoking, namely carbon monoxide and other chemicals in cigarettes, take longer (usually about 2 weeks) to leave the body. These chemicals have been shown to interfere with healing by preventing blood from clotting, slowing down the speed of tissue growth, and inhibiting the body's natural immune system. The test that your medical provider will do to see if you've been smoking is probably a blood, urine or saliva test for cotenine (a byproduct of nicotine), or a carbon dioxide test that is done by having you breathe into a machine that will test your respiration. "

Hope this answers your question!
