How Long Does Nicotine Stay in Your System for Testing?

The truth about nicotine’s half-life and how long it can be detected in your system.

Nicotine is a highly addictive substance found in tobacco products like cigarettes, cigars, and e-cigarettes. After consuming nicotine, it is rapidly absorbed into the bloodstream and distributed throughout the body. However, the exact amount of time it stays in your system depends on several factors, including:

Route of administration: Inhalation (e.g., smoking) results in higher nicotine levels than ingestion (e.g., chewing tobacco).

Dose and frequency of use: The more nicotine you consume and the more often you use it, the longer it will stay in your system.

Individual factors: Metabolism, age, and other factors can affect nicotine elimination rates.
