How Long Does Nicotine Stay in Your System for a Blood Test?

If you're a smoker, you may be wondering how long nicotine stays in your system for a blood test. The answer to this question depends on a number of factors, including how much you smoke, how long you've been smoking, and your metabolism.

Nicotine is a highly addictive substance that is found in tobacco products. When you smoke, nicotine is absorbed into your bloodstream through your lungs. Once in your bloodstream, nicotine travels to your brain and other organs.

Nicotine can stay in your system for several days or even weeks. The half-life of nicotine is about 2 hours, which means that it takes about 2 hours for your body to eliminate half of the nicotine that you have consumed.

Number of Cigarettes Smoked per Day	Nicotine Level in Blood (ng/mL)

11-20	20-40
21-30	40-60
