Basically saliva drug testing are used to detect the presence of drugs in an individual’s body. The process involves using a swab, with a similar appearance to a toothbrush but with a pad, to collect the saliva from the individual’s mouth. The sample is collected form the part between the lower cheek and the gum. After collection, the sample is placed in a vial before being taken for testing.
The saliva drug tests will normally detect a number of drugs including heroin, cocaine and amphetamines. The test is however majorly used to test for tetrahydrocannabinol abbreviated as THC which usually remains in an individual’s system after the intake of marijuana.
Most people prefer the use of eth saliva drug test due to the fact that it is much easier to collect the sample and the process itself is much less invasive compared to the blood test or the urine test. Another benefit that comes with the saliva test is the fact that it is easier for one to guarantee the collection of a clean sample actually belonging to the individual being tested as opposed to the urine test. With the urine test, the collection of the sample is done in the privacy of the bathroom and there is really no way of guaranteeing the sample being collected is clean and belongs to the individual being tested.
