Blood Drug Testing

If I use water in place of urine with an at-home drug test kit will the results show up negative?

I have to bring a photo-copy an at-home drug test which I am administering myself. I know if I use my urine it will come up positive. If I test with water instead will it show up as a negative result? Or will it come up as an invalid result? It is one of those cheap tests you can buy at any CVS. Please, no nasty comments saying not to use drugs. I only want the answer to my question. Yes I know that not using drugs in the first place will show a negative result, but it's a bit too late for that now. Will water work to make it appear as a negative? I would come up positive for opiates. Is there any way to get them out of my system quickly?

1. Urine is not water. If you use water it will be obvious you were trying to game the test.
2. What drugs have you used? I ask b/c if you smoked marijuana just once a week or so ago, your own urine will still probably come out negative. But if you're a full on pot head, I would just borrow a friend and ask them to pee on it for you. If they're a pot head too, stick with the water. But don't be surprised if it comes out "invalid".
3. Well if it's cheap why not buy two and try water with the first.
