How Long Does Cotinine Stay in Your System For?

Cotinine is a metabolite of nicotine, the addictive substance found in cigarettes and other tobacco products. It is used as a biomarker for exposure to tobacco smoke.

How Long Does Cotinine Stay in Your System?

The half-life of cotinine is about 20 hours. This means that it takes about 20 hours for the body to eliminate half of the cotinine in the system.

Cotinine Half-Life	Time to Eliminate 50%	Time to Eliminate 95%
20 hours	20 hours	100 hours

Factors that Affect Cotinine Clearance

The rate at which cotinine is cleared from the body can vary depending on several factors, including:

Factor	Effect on Cotinine Clearance
Age	Older adults clear cotinine more slowly than younger adults.
Weight	Overweight and obese people clear cotinine more slowly than normal-weight people.
Liver function	People with impaired liver function clear cotinine more slowly.
Kidney function	People with impaired kidney function clear cotinine more slowly.
Pregnancy	Pregnant women clear cotinine more slowly.
