I have been reading posts here and on various other forums and although I hear that saliva test CAN detect THC up to 96 hours who the hell has ever failed at over 24 hours and if so can you tell me how many hours it was since your last toke? Who ARE these people that fail at, say, 48 hours or more??? Post your stories and results PLEASE! It seems like everyone brags about passing after smoking the night before but there HAS to be a reason that the "72" or "96" hour window keeps getting thrown out there as a possibility.
