According to the CDC, potentially more than 34 million adults smoke in the United States. Unfortunately, smoking tobacco products is the leading cause of preventable death in the country (20% of such deaths). Fortunately, the United States has seen a significant drop in the total number of people that smoke and an increase in people who quit for health purposes.

It’s well-known that quitting can be difficult. One primary reason? Tobacco products don’t just contain tobacco; they also contain the addictive substance nicotine. When it comes to quitting, many wonder, “How long does it take for nicotine to clear the body?”

How Long Does Nicotine Stay in Your System?

When it comes to how long nicotine stays in your system, nicotine tests for smoking/exposure to tobacco smoke typically do not look for nicotine. Instead, the tobacco test will look for cotinine. What’s cotinine? It’s a metabolite of nicotine. This phrase means that when you inhale or chew tobacco, your body breaks down the nicotine from these products. This breakdown results in cotinine.

Why do so many tests look for cotinine instead of nicotine? Because cotinine stays in your system and tests can detect the substance in your system for longer periods of time than nicotine is. This fact is likely because the body eliminates cotinine more slowly than it does nicotine and that cotinine has a longer half-life than nicotine.

(“Half-life” in this context refers to how long it takes for these substances’ concentrations in your system to decrease by half. Note that it takes more than 2 half-lives for the body to completely eliminate these substances.)

It’s important to note that how long each substance is detectable varies widely, based on several factors like pregnancy, age, and gender, in order to determine how long nicotine stays in your system. Research furthermore indicates that people who use oral hormonal birth control methods metabolize nicotine faster than those who do not use such contraceptives.

How Long Does Nicotine Stay in Urine?

When it comes to how long nicotine stays in urine, tests for tobacco smoke exposure are most commonly urine tests. Not only are these forms easier and often cheaper than others, but urine has up to six times the concentration of cotinine as saliva or blood.

Saliva and blood are found at much lower levels in the urine in your body, making it important to test for all three. Nicotine and cotinine from products stays in the urine in your system for a similar amount of time.

  • Nicotine: Typically not detectable four days after last exposure
  • Cotinine: Typically not detectable four days after last exposure

How Long Does Nicotine Stay in Saliva?

  • Cotinine: cotinine can be detected in your saliva up to four days after last exposure

How Long Does Nicotine Stay in Blood?

  • Nicotine: 1 to 3 days in your blood after last exposure
  • Cotinine: 1 to 10 days in your blood after last exposure

How Long Does Nicotine Stay in Hair Follicles?

Hair follicle tests aren’t as popular as urine tests, but they can detect nicotine long after your last exposure. A nicotine test is most accurate one to three months after your last exposure. If you utilize a nicotine and cotinine levels test product too early, for instance after three days or three weeks, it’s likely that it will not be as accurate.

However, advanced nicotine hair test can actually detect nicotine exposure in your hair not only three days after, but even a year after your last smoke.

Can Doctors Tell If You Smoke From a Blood Test?

Yes. If you have it in your system, nicotine will show up during a blood test. Blood tests are able to find nicotine in your blood using tests that determine where the nicotine is present and how much nicotine is present. These tests can also find nicotine and cotinine. Medical tests can also detect nicotine in your blood, urine, saliva, hair, and nails. But, nicotine and cotinine may have different results in saliva tests and others given.

These substances stay in your system and stay in your blood for a varied length of time. Nicotine stays in the body and nicotine can be detected 1 to 3 days after last exposure, while cotinine may stay in the body 1 to 10 days after last exposure.

What are the Effects of Nicotine?

While nicotine can produce pleasing effects in your brain, these effects are short-term. Long-term, nicotine may have devastating effects on the body.
