I have a drug test for my PO and was gonna do the dilution thing, but dont they count it as a fail if the urine is obviously diluted? has anyone had experience with this?

I smoked about 2-3 times per week up until about 18 days til the test, then i stopped, and 10 days prior to the test (today) i smoked about half a joint. im 150 lbs and 5'10, so relatively skinny. Think i got a good chance of passing?
