How Long Does Nicotine Stay in Your System for a Blood Test?
Nicotine is a highly addictive substance found in tobacco products. It is quickly absorbed into the bloodstream after inhalation or ingestion and can remain in the body for several days. The half-life of nicotine in the blood is about 2 hours, which means that it takes about 24 hours for the body to eliminate half of the nicotine consumed.
The amount of time nicotine stays in your system for a blood test can vary depending on several factors, including:
- The amount of nicotine consumed
- The frequency of nicotine use
- The individual's metabolism
- The presence of other drugs or chemicals in the body
