I just passed a piss test at my new job by dumping like 1/4 of the pee out and adding some hot water. I was shaking like a chiwawa when they tested it but it worked!

I'll have to agree, do not allow tainted urine to mix with clean urine. If you do not have enough clean to fill a bottle, then do whatever improvisation necessary to make it as if you missed the bottle or spilled some or whatever, just don't mix them! You WILL come out dirty! I was a facility manager for 2 years in a residential drug rehabilitation company and was not only trained about these things, but am studying for my CADAAC (to be a drug counselor) & have had to take a few courses based around this kind of stuff.

No maybe not because they need a certain amount of it to trace it so if its a little most likely not...I'm n the same situation as you I did the exact same thing  but I had to fill it half way with my own piss...I just went today

Yeah it will be dirty because they are searching for drugs and if its mixed with dirty and clean pee then they'll trace the dirty pee

I've tried that before. Your urine will still be dirty and might come back diluted as well. It doesn't work.

Adding water may not allow an instant test (& sometimes labs too) to see that you are dirty, but it will result in an "invalid' test where you'll either be considered dirty anyway or asked to retest. If the concern is about a chemically based drug, then try Baking soda. I'll give you the guidelines:Females of average weight = 1 heaping Tablespoon (Tbs) and 1 (and no more than one) 16.9oz (regular sized) bottle of water. Males of average weight (and females with a hefty build) = 2-3 heaping Tbs  and 1-1.5 (16.9oz) bottle(s) of water. The easiest way that I have found to do this is to NOT mix it together & drink instead: Have your water bottle open and close by (bottles are easier, but tall slim cups work as well), one spoon-full at a time shove the baking soda back into your mouth as far as possible, then instantly start gulping down the water, allowing it to wash down all of the baking soda. If taking more than one Tbs- make sure you only drink enough to get it down so as to have enough for the next one without drinking too much water otherwise you may come out as a diluted(invalid) test result. After taking the Baking soda, allow 1-2 hours of easy bathroom access. You will know why if you do this method. After your third(3rd) time of urination your urine will only be clean for a short period of time so make sure to test within that next couple of hours. *Do Not test before the 3rd time and a good indicator that you are clean (& I realize this is grossly graphic) is when your bowel movements have stopped and are no longer the consistency of water.

Absolutely not!!! I can tell you from personal experience I tried that couple mths ago, and I only got a drop I mean a DROP of dirty in with clean and failed bigger than s**t. I would not advise it. I'd rather add water than let any dirty get in.

Did anyone ever pass this way?  I had clean urine but had to put very little in to hit line - I would say it was 98.9% clean and I did have lots of water today and took a diuretic.  I am really nervous - it was out of the blue and had no clue I had to go.  Will I fail it?

No, they will know it has been diluted with water and that you are trying to hide something. They may make you take another test.

Yes... They'll still find drugs in your system...and depending on where you get tested and how good their testing is some can even tell if you've used anything to get drugs or what ever out of your system... And usually, especially for probation in Florida, if any of it looks suspicious... They'll flag you for failing the drug test...

It does not work, I used clean urine and a drop of my own urine and I got the call 3 days later saying that I tested positive for marijuana. I only used my own urine because the urine was not enough for the cup.

Yes but if you really want to pass try energy drinks. Energy drinks can actually help you pass a drug test if you have been using. Make sure the energy drink has Vitamins B6 B12 and Niacin in it. The B6 B12 help block your body from metabolizing drugs in your system and the Niacin works as a masking agent. Drink a couple before your test you'll piss clean and won't come back as a watered down test, you'll be wired but it's worth it for those tests that catch you by surprise.

Mu guess is NO.I have taken drug tests before in order to gain employeement.And one thing is when you take a drug test they don't pad you down or anything, but they won't let you go in with an y containers but the one they give you or take in purses , bags or any of that sort.They will also shutt off the water so that you can't even wash  you'er hands until you give them your specimin. But even if you were able to put water in your urin... Your urin would have to also be a certain body temperatute.Because fresh urine would be hot, wow hot thats another question maybe 98.6 I forget.I do know a way to pass a urin drug test nut they probably would'nt allow me to post it.

If one of the urines is dirty, it will be positive. You can mix a clean urine with a dirty urine and the result is going to come out dirty.

Maybe a dab of bleach... Buy 500 mg Niacin non Flushing capsules. Take 2 chug a shitload of water before bed. Wake up repeat. I did it work 2 days and passed

Only if any of the mixed urine is contaminated with drugs. Most testing facilities test up to 10 specimens at a time in a mix. If it comes out negative then all 10 are negative. If they get a positive then they test all 10 independent to see if they are positive individually. Since 90% are negative, it is a faster way to do many test in a day.

As a lab tech I can tell you that we can tell when a sample is diluted or even mixed with something else. We can also tell what you have taken to try to cover up drug use...my advise to you... Just don't do the drugs and you wont get popped.
