Nicotine in Blood: How Long Does It Last?

Nicotine is a highly addictive substance found in tobacco products. When you smoke or use other tobacco products, nicotine is absorbed into your bloodstream and travels to your brain. Nicotine binds to receptors in your brain, causing a release of dopamine, a neurotransmitter that is associated with pleasure and reward.

The half-life of nicotine in blood is about 2 hours. This means that after 2 hours, half of the nicotine in your blood has been eliminated. The remaining nicotine will continue to be eliminated from your body over the next several days.

How Long Does Nicotine Stay in Your Blood?

The length of time that nicotine stays in your blood depends on a number of factors, including:

• The amount of nicotine you consume. The more nicotine you consume, the longer it will stay in your blood.
• Your body weight. Nicotine is distributed throughout your body, so people who weigh more will have lower levels of nicotine in their blood than people who weigh less.
• Your metabolism. People who have a faster metabolism will eliminate nicotine from their blood more quickly than people who have a slower metabolism.
• Your age. Nicotine is eliminated from the blood more slowly in older adults than in younger adults.
