How Many Days Before Should I Stop Smoking In Order To Pass Urine Cotinine Test?

smoking should ideally be stopped a week before
Detailed Answer:
There are three basic types of nicotine test: urine, saliva and hair. With the ability to detect nicotine for two weeks or longer after the subject has ceased smoking, the hair test is the most expensive and sensitive of these three types of test. However, it's also the least common.
If you're facing a nicotine test, for insurance, it's likely that you'll be asked to provide a urine or saliva sample. With the power to detect nicotine up to a week after the cessation of smoking, saliva tests tend to be more sensitive than urine tests.
Urine tests are designed to detect a byproduct of nicotine known as "cotinine." This substance is produced by the body's metabolic processes and can be detected in typical smokers for about four days after the cessation of smoking. Smokers with unusually fast metabolisms may be cotinine-free within two days after their last cigarette. On the other hand, some other smokers may be unable to pass a urine test for a week or longer after quitting smoking.
