Determining exactly how long continine is detectable in the body depends on many variables, including which kind drug test is being used. Cotinine - is created when the body breaks down the nicotine found in tobacco smoke - can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

The timetable for detecting continine in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions and other factors, making it almost impossible to determine an exact time continine will show up on a drug test.

The following is an estimated range of times, or detection windows, during which continine can be detected by various testing methods:

How Long Does Cotinine Stay in Urine?

Cotinine can be detected in a urine test for up to 1-3 days

How Long Does Cotinine Remain in the Blood?

No data is currently available on blood testing for continine.

How Long Can Cotinine Be Detected in Saliva?

A saliva test can detect Cotinine for 1-3 days

How Long Do Cotinine Remain in Hair?

Cotinine, like like many other drugs, can be detected with a hair follicle drug test for up to 90 days.

Testing for cotinine can also measure exposure to second-hand smoke.

According to the Centers of Disease Control and Prevention, in children, secondhand smoke can cause:
