How Long Does Nicotine Stay in the Blood System?

What Is Nicotine?

Nicotine is a liquid alkaloid that is derived from the Solanaceae plant and is one of the most addictive drugs in the world. It is an active ingredient in tobacco products like cigarettes, cigars, chewing tobacco and pipe tobacco.

Nicotine is usually inhaled by smoking cigarettes. Once inhaled, it reaches the lungs and enters the bloodstream. As the body recognizes that nicotine is a toxic substance, the body processes it through the liver and excretes it from the kidneys. On average, a cigarette contains 1 to 2 mg of nicotine, whereas secondhand smoke contains traces of it.

Factors That Affect the Life of Nicotine in One’s Body

The duration of nicotine in the body depends on various factors:

  • How much tobacco a person uses
  • The age and health of an individual
  • The kind of test adopted to check the presence of nicotine
  • How a person’s body metabolizes toxins

How Long Does It Take for Nicotine to Get Out of Your System?

According to Health Essential, a healthcare website in the US, nicotine stays in the blood for around 1 to 3 days after the consumption of a tobacco product. Cotinine levels are also used at times to detect the presence of nicotine in a person’s body. Cotinine is what nicotine becomes after it is metabolized in the body and can stay in the blood for 1 to 10 days.

Nicotine usually remains in the urine for approximately 3 to 4 days, as per Dr. Alan Wartenberg, but it can be detected till 15 to 20 days in more passive smokers. In a saliva test, which is the most accurate test, nicotine can be detected for more than 10 hours and up to 4 days.

How to Effectively Clear Nicotine from the Body?

Nicotine is intoxicating and highly addictive. There are a few ways you can use to flush out nicotine entirely from your body.

  • Drink plenty of water. The greater the water intake, the more nicotine is released from the body through urine.
  • Eat more fruits and vegetables. They are antioxidants with higher fiber and water content and help remove nicotine from the body.
