How Do Oral Drug Tests Work?
Surprise! It’s Random Drug Test Day at your place of employment. Will your weekend of relentless carousing catch up with you? You’ve had no time to plan for this ordeal. With a plain sampling of your spit, your recent drug history will be discovered. This is why employers and other institutions have embraced oral drug tests. They are extremely well-matched to randomized drug testing. They are also quick, painless and cheap to do. Since they are easy to administer and much more complicated to rig than some other methods of drug testing such as urine analysis, oral drug tests are becoming very widespread.
Saliva based drug testing can be used in a variety of situations. Many businesses have permanent random drug testing to preclude liability issues arising from workers who are under the influence while on the job. Many law enforcement officials such as the police use oral drug testing at the location of traffic accidents or in cases where they could have a reasonable suspicion that an individual is under the influence of illegal substances. Other situations may involve the return to employment of somebody who has been on probation owing to an past drug episode.
Random testing is the most effective form of drug testing because a random test provides the test subject little time or occasion to elude the test method. Saliva based tests are ideal for random drug testing. They are instant, easy to do, and not as invasive as other methods of testing that necessitate urine, blood or hair sampling.
While other drug testing methods such as hair or blood testing are considered the most reliable, oral drug tests that utilize saliva samples yield very good results. Also, since the testing method is a uncomplicated mouth swab, there is no pain and no embarassment involved as there could be in blood or urine testing. Saliva tests are really good at showing how recently an individual has tried drugs. This is uniquely important in cases like traffic accidents. The police officer would want to know that the driver used cocaine shortly before the accident. The fact that someone may perhaps have used cocaine a month before would not be important to the case.
