Saliva Drug Test
A saliva drug test or oral fluid drug screen is a simple mouth and cheek swab drug test that will test for multiple drugs (including marijuana) at one time with 97% accuracy.
Drug test results are available in 10 minutes. This is a drug test that is favored because it tests for extremely recent drug use and is extremely unobtrusive - all that is required is a saliva sample.
You can learn with a saliva test whether marijuana, cocaine, opiates, meth, amphetamine-based prescription drugs (like Adderall or Ritalin), or PCP have been used between an hour ago or as many as 72 hours ago. Times vary from drug to drug - marijuana generally shows up in saliva an hour after use, as do opiates. But cocaine, methamphetamine, and amphetamines (such as Adderall or Ritalin) can show up as early as 5-10 minutes after use. No other drug test can give you results like that.
How the Saliva Drug Test Works
The kit comes with a saliva collector, and you can take saliva at any time of the day. For at least 10 minutes, the person taking the test should not place anything in their mouth, including food, tobacco, drink, or gum. The test is performed by making sure that the sponge on the end of the collector is fully saturated with saliva, which should take 3 minutes. When the sponge is saturated, you push the collector into the test device. After ten minutes you will be able to tell the result of the sample. If a line appears next to the abbreviation for the drug, then you know the sample was negative for that drug. If no line appears at all, however, you will know the sample is positive for that drug. The "Control" line must always appear - if it does not, then the saliva test was performed wrongly or is otherwise invalid.
