So i have to take a drug test probably this week and it is a home drug test, just so you know, and i was wondering what's the possibility of me passing if i fill the cup up to the base line with water and pee a little to make it seem yellow/ urine like. or i can add more water, past the base line, just to dilute it more. I want to know if anyone has tried this and if it has worked... and what is the possibility of it working if anyone knows?
