Sometimes before hire, you need to go through the drug test. Of course, it is not always mandatory, but there are cases when it is a must. Employers are looking for drug-free workers, and even if you took the drug only once, a drug test could become a real surprise because you don’t have time for detox and afraid of being recognized as an active drug taker. The most common drug test method is a pee test. However, there are some cases when you need to go through another process called mouth swab test.
Saliva or the so-called oral drug test has been invented to detect drugs during first few hours after their use. Many employers choose this method because you can conduct this test at the company site and it is possible to detect recent drug usage quickly.

People who are preparing for this type of test are trying to eliminate drug intake before testing by brushing teeth with toothpaste and additionally cleaning mouth with mouthwash removing the elements this test traces.
The sample is analyzed using ELISA technology (enzyme-linked immunoassay technology) which can detect marijuana intake in 60% cases and other drugs, which are less sensitive, so urine test is not able to find them.
