Moreover, it is also convenient and preferred than other measures because it is noninvasive and not necessary to collect urine specimens or blood samples.

So how is this test done? Firstly, the saliva sample is collected from the patient. Then a test strip is soaked in the sample and left for 20 minutes.

So, for how long? It is indicated that the more this gene your body has, the shorter time nicotine does exist in your saliva.

Estrogen hormone accelerates the action of CYP2A6, so women have a faster metabolic rate of nicotine than men because they usually have a higher level of estrogen.

Nicotine stays or eliminates in the saliva depending on the variation of blood flow through it. Meals are considered as one of the physiological events that can affect the nicotine metabolism. After a meal, blood flow to the live raises about 30% and the nicotine clearance increases about 40% as a result.

Medications

Taking some medications can affect the nicotine metabolism as well. A few drugs which induce the increase of CYP2A6 gene like dexamethasone, phenobarbital or oral contraceptives will remove nicotine from the saliva and the body faster.
