How long does it take for nicotine to be out of your blood stream?

Nicotine has a half-life of about 2 hours, which means that it takes about 2 hours for half of the nicotine in your blood to be cleared. It can take up to several days for all of the nicotine to be cleared from your blood. However, the amount of time it takes for nicotine to be completely eliminated from your body can vary depending on several factors, including:

- Age

- Weight

- Sex

- Metabolism

- Smoking history

- Health conditions

- Medications

For example, nicotine may be cleared more slowly from the body of someone who is older, obese, or female. It may also be cleared more slowly from the body of someone who has a slow metabolism, a history of smoking, or certain health conditions, such as liver or kidney disease. In addition, some medications can interact with nicotine and slow its clearance from the body.

If you are concerned about the amount of time it takes for nicotine to be cleared from your body, talk to your doctor.
