How Long Does It Take for Nicotine to Leave Your Body?

Nicotine is a highly addictive substance found in tobacco products such as cigarettes, cigars, and chewing tobacco. When consumed, it enters the bloodstream through the lungs or mouth and reaches the brain in just 10 seconds. Once in the brain, nicotine binds to receptors that trigger the release of dopamine, a neurotransmitter that produces feelings of pleasure and reward.

Half-Life of Nicotine

The half-life of a substance refers to the amount of time it takes for the body to eliminate half of the substance. The half-life of nicotine varies from person to person, but it is typically around 2 hours. This means that if you smoke a cigarette, half of the nicotine will be out of your body within 2 hours. The remaining nicotine will continue to be eliminated gradually over the next several hours.
