Ammie Reviewed by Ammie on . Drug test question. I have to take a piss test sometime today, I was curious about adding bleach to the sample. I've seen this on a number of differrent sites, and they all agree that 6-10 drops will, in most cases, render it negative. I put some bleach in a visene bottle, pissed in a cup at home, and noticed that up to 15 drops will not cause it to foam, and there is almost no odor, unless you practically stick your nose in the cup and try to get a whiff. Of course, they've never smelled my piss before, so it Rating: 5
