Will Nicotine Show Up on a Blood Test?

Smoking cigarettes or using other nicotine products can leave a lasting trace in your body. Will nicotine show up on a blood test? The answer is yes. Nicotine, the addictive substance found in tobacco products, can indeed be detected in your bloodstream through a blood test.

How Long Does Nicotine Stay in Your Blood?

The length of time nicotine stays in your blood depends on several factors, including your age, how heavily you smoke, and your overall health. Generally, nicotine can be detected in the blood for up to 24 hours after your last cigarette. However, for chronic smokers, nicotine may remain detectable in the blood for several days or even weeks after quitting.

Nicotine Concentration in Blood	Time After Last Cigarette
10-30 ng/mL	1 hour

2-5 ng/mL	12 hours
1-2 ng/mL	24 hours

Can Nicotine Tests Detect How Much I Smoke?

Nicotine tests can provide an indication of your smoking status, but they cannot accurately measure how much you smoke. The amount of nicotine in your blood can vary depending on factors such as the nicotine content of the products you use, how you inhale, and your metabolism.

Smoking Status	Nicotine Concentration in Blood (ng/mL)
Non-smoker	< 1
Occasional smoker	1-10
Light smoker	10-20
Moderate smoker	20-40
Heavy smoker	> 40
