I used to not only perform drug screens for large companies, I also taught people the entire COC rigamaroo....

Saliva tests have a very high incidence of technical error, if the technician does not get a good enough 'scraping' of the cheek then a proper sample cannot be obtained. False Positves are rare from technical error though, unless they got the papers mixed up. Saliva tests are also not recognized by many courts, including DOT guidelines, because there is only 1 test run rather than a test, the a confirmation.

Depending on your state you could take it to court and WIN, but not worth it for a pre-employment, just keep that in mind in case of an injury....
crystaliscious Reviewed by crystaliscious on . ORAL SALIVA DRUG TEST ? I had an interview about two weeks ago. I honestly didnt think I was going to get the job so I continued to smoke. I got a call on tuesday asking if I could come in for a second interview. I was up alll night and decided to smoke half a blunt at 5am so I could go to sleep. I finally went to sleep at 7 but had to be at my interview at 10. I got the job but he told me to come back at 3pm for a drug test. My bf told me it was most likely going to be a mouth swab test since it was done at the job Rating: 5
