Saliva Drug Test Nothing Came Up

Updated

So I went in for a job interview & orientation, I automatically knew they'd drug test me. Little did I know though it would be a mouth swab test, so I wasn't prepared for that kind of test. I have never done that kind of test before. I do smoke marijuana daily, now my concern is not how to pass it, I've looked up plenty of info on that. So when they gave me a lunch break I just went home brushed my mouth real good and used mouthwash as well. Also sucked on a couple of ice cubes ate a greasy hamburger and then the rest of the time up until the test just sucked on Altoid mints and drank water.. These were just all things I had read to do to try to help pass this type of test. Well when they gave us this mouth swab drug test they let us do it ourselves. She said to just put it in your mouth for little bit and make sure you get plenty of saliva on it. So I did what she said and put it back in the tube for it to be read. Nothing came up, it wouldn't read. She said to take it out try it again. I did that 2 more times still nothing, it wouldn't read. So she gave me another 1 to try. I did the same thing and put it back in the tube to read, still nothing read. She told me to take it out and put more saliva on it, so I did. The swab was wet but still no results showed. There were a few others there that did the test as well and had no problems. Can anyone tell me what the deal is and why I keep getting no results?

At that point, you probably had it far too diluted for it to be able to read it. This has been known to happen with saliva, blood and urine tests, when someone has been drinking a lot of fluids.

Are they going to let you retake it?

I take the same exact thing and I'm pretty sure you will be good. Good meaning you will pass the test I'm not sure what milligram you take but a half is not a lot. I would suggest if its urine test to drink plenty of fluids expecially water maybe a shot of vinegar. If its a mouth swab benzo's do not show up on the mouth swabs I take. so if you have a choice take the mouth swabif not drink a lot of water and I mean a lot basically it will shut your kidneys down where you are only urinating water.. I'm not sure if this is true but someone told me it years ago to soak your finger in bleach then dip it in the urine and that should kill some of the drug..hope that helps ..remember I have is not a lot. Good luck!

Had a surprise mouth swab today, and had taken 2 mgs of xanax 28 hours before the test. I was informed of the test 3 hours before the test. I immediately started brushing teeth with peroxide and kept cleaning mouth out with peroxide for those three hours. Then right before test I put 8 altiods in my mouth. Any input on if I passed?
