How long does nicotine last?
Whenever you smoke or chew tobacco or inhale passive cigarette smoke, nicotine is absorbed in your bloodstream.
From there, the enzymes in your liver break down most of the nicotine to become cotinine. The amount of cotinine will be proportional to the amount of nicotine you take. These substances are eventually removed through your kidneys in the form of urine.
Cotinine, the main product of nicotine breakdown, can usually be found in your body for up to three months after ingestion. How long it stays in your system will depend on how you take nicotine and how often.
Keep reading to find out how long nicotine can be found in your urine, blood, saliva, and hair.
How long will there be traces of nicotine in your urine?
Although there are several differences between cigarette types, it is believed that one cigarette contains 12 milligrams (mg) of nicotine.
When nicotine is in the blood, it is measured in nanograms per milliliter (ng/ml). In the bloodstream of a non-smoker without exposure to passive Smoking, the level of cotinine is less than 1 ng/ml. the Average level of a daily smoker is usually higher than 10 ng/ml and can even reach 500 ng/ml. the Average value is from 30 to 50 ng/ml.

If you smoke infrequently, cotinine will usually be present in the urine for about four days. With regular exposure to nicotine, cotinine can be detected within three weeks after the last exposure.
A positive urine test depends on when you provide a urine sample relative to the last time you take nicotine. If you are a smoker, the test can be positive for 1,000 nanograms per milliliter (ng/ml). If you haven’t smoked for two weeks, a positive test may be over 30 ng / ml. Each lab may have different control ranges for positivity, so it’s important to discuss the results with your doctor.
Nicotine in blood. Should there be traces of nicotine in your blood?
Nicotine lasts in your bloodstream for one to three days, and cotinine can be found in the blood for up to 10 days.
Nicotine in the blood can be detected using qualitative tests (whether nicotine is present) and quantitative (how much nicotine is present). These tests can detect nicotine, cotinine and other breakdown products called anabasine.
False positive reactions to nicotine are common in blood tests. This is usually due to the presence of a compound called thiocyanate. It is found in foods such as broccoli and cabbage, as well as some medications.
Nicotine in saliva and hair. Will long traces of nicotine be present in your saliva and hair follicles?
Nicotine and cotinine can take up to four days to completely wash off your saliva.
Traces of nicotine can usually be found in your hair follicles within three months of your last exposure. Depending on the hair test used, nicotine can be detected up to a year after the last exposure.
Although hair testing is possible, it is not used as often as urine, saliva or blood tests. This is because hair testing is usually more expensive.
How to determine how much nicotine is in your system?
You can buy over-the-counter urine or saliva tests to check for nicotine in your system. These tests usually give the answer “Yes” or ” no ” – they often don’t tell you how much nicotine is in your system. These drugs are not recommended by doctors regularly, so their reliability and accuracy remain unclear compared to tests that pass through the employment office or doctor’s office.

- Liver function: Different people can metabolize nicotine at different rates depending on their liver enzymes.
Medications you take
