Nicotine in Blood: How Long Does It Last?

Nicotine is a highly addictive substance found in tobacco products. It is absorbed into the bloodstream through the lungs when you smoke or vape, and it can also be absorbed through the skin. One of the most important things to know about nicotine is how long it stays in your blood.

The average half-life of nicotine in the blood is about 2 hours. This means that it takes about 2 hours for the amount of nicotine in your blood to decrease by half. However, the half-life of nicotine can vary from person to person. Factors that affect the half-life of nicotine include:

Your age: Nicotine is metabolized more slowly in older people than in younger people.

Your weight: Nicotine is distributed throughout the body, so people who weigh more have a higher volume of distribution and a longer half-life.

Your health: People with liver or kidney disease may have a longer half-life of nicotine.

The amount of nicotine you consume: The more nicotine you consume, the longer it will stay in your blood.

The following table shows the average amount of time it takes for the nicotine level in your blood to decrease by half, depending on the amount of nicotine you consume:

Amount of nicotine consumed	Half-life
1 cigarette	2 hours
5 cigarettes	4 hours
10 cigarettes	8 hours
20 cigarettes	16 hours

How Long Does Nicotine Stay in Your System?

The amount of time that nicotine stays in your system depends on a number of factors, including the amount of nicotine you consume, your age, your weight, and your health. However, nicotine can be detected in your blood for up to 3 days after you last used a tobacco product.

The following table shows the average amount of time that nicotine can be detected in your system, depending on the type of test that is used:

Type of test	Detection time
