ok so i kind of fucked up over new years, and I won't pass. i possibly have a piss test for my p.o. tomorrow. I know this is kind of disgusting but i got a srs question. I urinated in a glass in the last week or two. I know I was clean from all drugs when i urinated in the glass. question is, the urine from the glass might possibly come up positive for alcohol. I know alcohol evaporates faster and that it is lighter than water. My assumption is the urine probably won't test positive for alcohol because the alcohol would have evaporated in the week it has been sitting. either way it's safer using this old sample than using mine, since I took a couple hits of weed and am sure I will come up positive. can anyone tell me what my odds may be? i've already worked out the logistics, I have a tiny eye-drop medication bottle filled with the sample already.
