Well I decided to get analytical about this......

Ive been trying to smoke and self saliva test to truly determine what my detox time is. I did pass the test given to me at work...at least i think i did...still have my job.....and i cant ask.....but as a very mild smoker these days I'm tryng to determine if I can smoke Friday night and Sat morn and still test negative Monday afternoon....48-56 hrs... So i bought 10 saliva test kits from Drug Alcohol test.com....1st trial tested after 96hrs of mild weekend smoking and negative..2nd test was mon morning after fri night, sat during day and a little sun morning....tested negative mon morning.....3rd and 4th were done on sun morning after slightly more smoking on fri and sat.....negative again...Im beginning to think that these tests are bunk!!!! anyone have experience with these....the ones that you press your saliva from the swab into a dropper and then drop onto a test card? Its supposed to be the standard 5panel test..but i keep coming up negative!!!!! Granted i dont smoke very much...around 12 bong hits in any given weekend...normally mid grade commercial....Is it possible that i can still remain below the test limt? Would like some feedback b4 i blow another $100 on home tests (this time from a different manufacturer though)...Thanks in advance
