Blood Drug Testing

If I smoke weed today will I be able to pass a saliva drug test in 2 weeks?

I may have to take a saliva drug test (not urine) in 2 weeks and I just want to know if smoking weed today would cause me to fail that test. Also, if I am a non-regular user (about once a week) then how long before the test would I have to stop?

1. if it just detects salvia then it won't show. weed stays in the system more than a month
2. Almost certainly. Assuming you aren't obese, two weeks gives enough time for metabolites to degrade to undetectable levels in bodily fluids. You wouldn't pass a hair test, though. Saliva is a particularly incapable test; in other words, it is less likely than other methods of successfully detecting THC and cannabis metabolites.
