How Long Does Tobacco Stay in Your Bloodstream?

Tobacco contains nicotine, a highly addictive substance that is rapidly absorbed into the bloodstream after inhalation, ingestion, or skin contact. The time it takes for nicotine to clear from the bloodstream varies depending on a number of factors, including the amount consumed, the method of administration, and individual metabolism.

According to the Centers for Disease Control and Prevention (CDC), nicotine levels in the blood peak within 10-30 minutes of inhalation and can remain detectable for up to 24 hours.

Inhalation	2 hours	12-24 hours
Ingestion	4 hours	24-48 hours
Skin contact	6 hours	48-72 hours
