So, I took an under-the-tongue saliva test for a job on friday morning.. my last time smoking was Sunday night around 11:30. I smoked kief.

Anywho, the test goes to labcorp. And it says on the website: Q: What is the drug detection window for oral fluid testing?
Depending on the drug used, dose, and route of administration, a drug may be detected in oral fluid in less than one hour and remain detectable for five up to 48 hours after last use.1,2

Is this true?
