ill start with this, I am not doing this for probation and I am in no legal issues. This is soley for pre-employment. I smoke and do not intend to stop, so please hold any comments like STOP SMOKING back. I went with the urine substitution method, i got my friend to pee in a 2oz energy drink bottle, (he is clean and doesnt do any drugs and never has), and I took it and kept it in my armpit while waiting for the test, went in, poured it in (at labcorp), and it filled to about 60 ML. They wanted it at 65 ML. Anyways, They didnt put the blue stuff in the water for some odd reason, and I had peed a SMALL ammount, like 2 second piss, into the toilet to make it seem legit. I added 5ml of the clean water and small part of my piss into the cup to make it 65 ML I am pretty sure I am OK, but my question is how badly will that 5ML of water/pee fuck up the 60 ML of clean urine, if any at all? I know they have a cutoff point for what is negative and what is positive. Has anybody gone through a similar situation? If so post what happened in your situation, I would definately love to get this job, and I wasnt even thinking about it until now, but some assurance would make me feel much better! What do you think?
