is there anything you have in the house that you can take to pass a saliva swab drug test?
Yes, brush with hydrogen peroxide and rinse with mouthwash.
On your way to the test eat as many breath mints as possible and before you walk in rinse with mouth wash one last time.
Don't put the test strip under your tongue. Try to pull the saliva from your lips not your throat.
These tests only test for THC for about 3 days back, so if its been longer than that your in the clear.
Your best bet is to not use drugs.
