Probation officers differ on their policies towards drug testing. In my case, a test that shows up positive for THC = a referral to the judge and drug counseling, along with more attention payed to the levels of EVERYTHING in your urine.

My best advice, don't find out what happens if you fail. I smoked all summer once (Went out of town for a month from my county I'm serving probation in) without any testing, and I quit for about 15-20 days prior to my first test coming back, and still passed.

Like many have said, the best way to assure passing and avoiding the "What if I DO fail?" dilmna is to just stop smoking in a reasonable time prior to your test.

Seems as though your test is in 6 days from when I'm posting this, good luck bro.
