Input: Once nicotine consumption is stopped, then both nicotine levels and nicotine metabolite levels in the blood decrease, but it must be kept in mind that these levels do not disappear altogether. The simplest answer to the question of how long does it take for nicotine to leave your system is a few weeks. Once nicotine consumption is stopped, nicotine levels in the blood begin to gradually decrease. Nicotine has a half-life in the human body of 2 hours (although it can range from 1 to 4 hours in different individuals). The average smoker has a blood nicotine concentration of about 40 ng/ml after an evening cigarette. And usually when signing up for life insurance they will ASK you if you've smoked in the last 12 months, but the testing is not that thorough, its the same nicotine test no matter what, they dont take your hair or anything, its a simple blood test. Ive heard it takes 30 days but not 100% sure. Nicotine has been shown to be an even more addictive drug than others such as heroine! The lingering presence of nicotine in the body acts as a reminder for nicotine consumption. It is popularly believed that nicotine is released from the human body within 72 hours of its consumption, but the truth is far different. The various aspects of nicotine storage in the body last for weeks after the most recent consumption of nicotine. Many people wonder about how long nicotine stays in your blood. Blood harbors both nicotine and metabolites released by nicotine. I recently got hired for a job and had to undergo cotinine testing, however because I drank a lot of water, the lab requested a second test due to dilution. Before my first testing, I had been smoke free for 3 days. I took the test, then ignorantly lit a cigarette, it tasted awful.. I probably took 2 or 3 puffs off of it before throwing it out. Sorry to split hairs on this, but given that the typical half-life of nicotine is 2 hours, and that most assays have a limit of detection of 0.1 to 0.5 ng/ml, following the logic I described above, all the nicotine has gone from the blood stream within 24 hours. i.e. when you take a blood sample from a smoker 24 hours after their last smoke, they will most likely have a blood nicotine level <0.5 ng/ml. (i.e.>95% gone by 24 hrs). She's more concerned with how long it takes nicotine and what I would call, by products, from leaving her body, than she is as to why the doctor has asked her to quit smoking. She even said the doctor told her he wanted the nicotine out for 30 days so the surgery would be successful. How long can nicotine be detected in blood or urine after quiting smoking? [Top] The byproducts of nicotine can be detected in the blood for up to a month after you stop smoking. This is only of concern if you are in a situation where someone else might want to test you for the presence of nicotine or nicotine byproducts in your system. However, the metabolite of nicotine which is known as Cotinine leaves its traces in blood as well as in urine for up to 7 days. About 85 to 90 per cent of the nicotine which is present in your blood is metabolised by the liver and is thrown out of your system by the kidney. But due to the higher concentration, many a times, it still persists in the blood stream. Nicotine is a very highly addictive chemical that is the main component of cigarettes. Your body, especially your heart and lungs, will usually begin to heal at 12 hours after you've had your last cigarette/ stopped smoking. Finally, as nicotine levels in the blood keep decreasing over the coming weeks, the nicotine stored by various tissues in the body recedes to significantly lower levels. Patients with surgical procedures planned are often advised to quit smoking weeks before surgery so that healing can be improved. Query: how long before nicotine out of your blood
