As soon as you hear the word nicotine, the next thing that comes to mind is tobacco, usually smoking tobacco cigarettes. Nicotine is an alkaloid substance found in the tobacco plant called Nicotiana Tabacum. Nicotine constitutes about 3% of tobacco’s total dry weight. It’s the extremely addictive element of tobacco and makes tobacco use more addictive than even Heroin and Cocaine.

Before we talk about how long does nicotine stay in your system, nicotine test and why you might need one, we should remember that tobacco is not the only source of nicotine or nicotine poisoning.

In addition to tobacco, it can be found, though not in as much proportion, in other species of nightshade plants such as tomatoes, eggplants, green peppers, potatoes, and leaves of coca plants. With the advent of e-cigarettes and vaping, nicotine is now found in a pure liquid form in vape juices and e-liquids that also contain propylene glycol, vegetable glycol and flavorings.

It has also been heavily used in insecticides since the late 17th century but was eventually banned in the US in 2008 by the United States Environmental Protection Agency. Another thing to keep in mind is that the amount of this compound found in your blood, urine, saliva or hair is relative, and depends on many factors such as the person’s genetic makeup, the way they take nicotine etc.

Types of Nicotine Test

There are three major types of nicotine test:

  • nicotine blood test
  • urine nicotine test
  • saliva nicotine test (swab)

A fourth, rather less common type is the hair test, which is only used for research purposes, for instance in a study that tries to measure how much a non-smoker is exposed to tobacco smoke or vapor, produced by electronic cigarettes.

Nicotine Blood Test

The rate at which nicotine can be absorbed by the blood varies from person to person. It depends on the consumed amount in the particular brand of the cigarette and the way the person takes it. However, it’s instantly absorbed by blood i.e. within seconds of puffing on a cigarette or after taking a long draw from your best vape.

Nicotine can be tested in blood both qualitatively and quantitatively. An expert can take a blood sample and determine the levels or mere presence of nicotine in it. The nicotine blood test is a very effective approach and can detect the tiniest traces of cotinine in the bloodstream.

Is Nicotine Blood Test Accurate?

Instead of nicotine, blood tests detect the presence of cotinine in the bloodstream. Cotinine is a metabolite formed when nicotine is metabolized by your body. It stays in the blood for longer than nicotine and therefore prolongs the detection window for the nicotine test.

There are a few things that we liked about the Nicotine Tests/Quantified Analysis:

  1. Includes a convenient home blood sample collection kit
  2. Just a few drops of blood are required to offer comprehensive, quantified lab results
  3. Can also detect secondhand smoking or use of Nicotine Replacement Therapies such as nicotine patches, nicotine gums etc.

This is an ideal test for workplaces, quit smoking programs, hospitals, academic research, and even self-testing. The New York State laws prohibit the sale of such kits to the residents, therefore if you live in NY, you won’t be able to acquire it.

How Long Does Nicotine Stay in Your System?

Nicotine blood test
Saiful52/Shutterstock

When nicotine enters the bloodstream, it’s metabolized into cotinine, which then slowly mixes with the blood. Your liver then toils to remove the toxins along with cotinine from the blood. While the removal of waste products by the kidney from urine is very fast, detoxification of nicotine from blood is usually very slow.

Nicotine can be seen in blood 1-3 days after using a nicotine product. But depending on the intake and person’s genetics, sometimes it can take up to a week for the cotinine level in the blood of a tobacco user to come down to the level of a non-tobacco user.

Blood testing is usually done when very accurate results are required. Its pros and cons will show when it can be a viable option:

Pros of Blood-Based Nicotine Testing

  • The most meticulous way for detecting nicotine in your body, with a comparatively longer detection window.

Cons of Blood-Testing

  • Expensive and time-consuming.

Saliva Nicotine Test (Swab)

The most accurate and most preferred method by health professionals to test nicotine is saliva test. It not only rids you of the hassle of handling urine but is also capable of providing an approximate amount of compound the person has in his body, which can be easily translated into the amount of tobacco they have used.

A saliva test can determine nicotine levels of 0 to 2000ng/ml, the widest range offered by any of the three types of the test.

Just like urine tests, saliva tests require the individual’s saliva to be soaked in a strip, for about twenty minutes. The saliva then reacts with cotinine metabolite in the strip and reveals the amount of nicotine in the system by indicating different levels of cotinine in the spit.

Pros

  • The saliva test is the most non-invasive, and the easiest nicotine test to administer.

Cons

  • Saliva test has a very short detection window. Usually, it’s reliable only if the donor has used nicotine very recently.

How Long Does Nicotine Stay in Your Saliva

Depending on the usage and amount in the system, nicotine in saliva can be detectable for anywhere between 10 hours to 4 days after the last intake.

Nicotine Test — What Is It and Why Do It?

A nicotine test is done to find out whether a person is actively using tobacco or not. Tobacco use is the leading preventable cause of death in America.

According to a Fact Sheet by the Centers of Disease Control and Prevention, 480,000 people die in the States alone. Long-term use of tobacco increases the risk of many lethal diseases and can have a great impact on an individual’s health.

This is why many employers require nicotine testing to evaluate their prospective employees. In addition, there are many other reasons where an individual might be required to take a nicotine test:

  • When a court may order nicotine test, usually in cases of child custody
  • To find out if an individual is taking a nicotine overdose that might be causing/augmenting the illness he/she is under treatment for
  • When a woman is pregnant and wants to assess the health of unborn and in breastfeeding mothers to find out if the infant is getting its harmful effects through the milk
  • When a health and life insurance companies require nicotine testing before they start their plan
  • To monitor compliance of an individual who joins a smoking cessation program
  • When an individual is about to go under spinal fusion, wound revision, orthopedic, plastic surgery, pulmonary therapy, or organ transplantation

A nicotine test can offer qualitative as well as quantitative results. Qualitative nicotine tests may reveal whether or not the compound is present inside the system of an individual, while quantitative nicotine tests show its concentration level.

In other words, Qualitative testing will help distinguish non-tobacco users, those who have recently quit, those who are exposed to second-hand smoke, and those who actively smoke from each other.

Final Thoughts about How to Effectively Clear Nicotine from the Body

Although nicotine is extremely addictive, quitting is possible. Chances of abstinence increase if both medicinal and non-medicinal aids are used to cope with the withdrawal symptoms. However, if you want to quickly get nicotine out of your system, you might not be able to use the nicotine replacement therapies.

There are some drugs, however, like Chantix and Zyban that can act as a medicinal cessation aid but don’t contain nicotine. These pills have their own side effects which can be extremely severe, so make sure you consult a health professional and offer them full disclosure on any health issues you’ve had in the past before taking any of these medicines.

Here are a few things you can do to clear nicotine from your body and pass a nicotine test.

  • Quit taking nicotine, preferably three weeks or at least 5-7 days before the test
  • Drink a lot of water as it helps nicotine leave your body through urine
  • Drink more fluids such as green tea, cranberry juice, and other fresh juices
  • Eat fresh vegetables, greens, and fruits. All of these can act as antioxidants and also speed up the process of detoxification of nicotine from your body. They are also rich in fiber and water content, two things that can expedite the process of metabolizing nicotine in your body.
  • Take a lot of Vitamin C. It’s found in oranges, lemons, limes, mangoes, strawberries, pineapples and other citrus fruits. Vitamin C is not only a great antioxidant but also accelerates metabolism.
  • Increase your physical activity, go for long walks, and start doing regular exercise. Increased blood circulation helps your body get rid of all the toxins including cotinine through sweat.
  • Eat foods that help raise bile production in your liver for speedier removal of nicotine and help your system get clean.
  • Garlic, egg yolks, and onions are some of the foods you should consider.
  • There are some medicines/detox drinks that claim to help your body get clean instantly, however, make sure you consult your doctor before taking any such medicine. We personally think most of these drinks are nothing but a waste of money.
  • Avoid going to places where people are smoking
  • Try to live a happy, depression-free life otherwise, you might feel like going back to your addiction.

One last cunning trick to pass the test: if you only have traces of nicotine showing up after the test, blame it on secondhand smoke. Needless to say, this excuse won’t work if your body is packed with nicotine.

Sunday, Monday, and Tuesday I drank over a gallon of water each day, ate oranges and lemons , went to spin class for over an hour a day plus other work outs and sat in the sauna.

    I’m getting a blood test in two days but it’s not for cotinine or nicotine levels. They’re looking at my kidneys and liver for the medication I take. If they aren’t looking for nicotine or cotinine, can they still see it? I also haven’t smoked in two days so it will be 4 days total without smoking when it comes time for my test. Someone please answer quick

    Today is December 20. I had to quit on November 30 because I’m having back surgery and a fusion on January 16th. The doctor won’t do surgery if I don’t stop smoking. I had to go for a nicotine blood test today, December 20th. Is it ok if I have a couple cigarettes today? My next nicotine blood test is January 8th, a week before the surgery. I just wanted to smoke today and then that’s it forever. Please let me know. Thanks
