If you are going for a Nicotine test where you need to test negative, however, it should be noted that some companies will test using hair samples. If this is the case, nicotine can remain in your hair for weeks. In this event, you may want to visit a local salon and see if they have a treatment they can apply.
Everyone’s body is different, so it may take a little longer or shorter than an average person. The liver may take longer to metabolize the nicotine out of the system and the kidneys could take longer to flush it from the system. The byproduct of nicotine, known as cotinine, takes longer to pass through the system.
It’s important to remember that nicotine is a drug that is very addictive. Many people don’t even realize how much they smoke and how much it affects them until it is brought to their attention by an observer or when they try to stop.
It all ends up coming down to how frequently you smoke and why you care if the Nicotine stays in the blood. If it’s because you’re going to be taking a test for Nicotine levels, then you will want to avoid cigarettes for longer than 48 hours. Especially if you are a heavy smoker. The more you smoke, the more nicotine is built up in the system, meaning that it will take that much longer to leave the system. If passing the test means a significant amount, you may want to avoid cigarettes for a few weeks just to be on the safe side.
