Diluting Urine to Pass a Drug Test

Diluting Urine to Pass a Drug Test

The process of diluting urine in order to pass a drug test is a common strategy. Dilution is adding some substance to your urine that will mask or destroy the drug residue. There are quite a few substances that you can use in an effort to skew the results of the test. None of them are risk free.

Pass a drug test: Diluting UrineIf you know you will fail the test, you really have nothing to lose by giving it a shot and see what you can do. There is an array of common substances out there that you can try.

If you’re not familiar with the process involved in a urine drug test, watch the video below

Be well aware though, that there are things that can go wrong. With sophisticated tests, there could be controls in place. For example, they typically test the pH balance, the temperature, and other properties of the urine. They may have someone overseeing the test too, which ensures the urine you are submitting did indeed come from your body at that point in time.

Diluting your urine sample with adulterants is risky business. In the early days, it was common (or, not uncommon) to spike the urine with vinegar, or eye drops which would alter the drug residue to make it undetectable. It didn’t take long before the labs got hip to that and refined the process to be able to detect the presence of such substances.

Since then, if some kind of foreign substance is detected in your urine, it will be considered a positive analysis. On balance, diluting your urine specimen is a losing proposition.


If you want a viable alternative to diluting urine, something that you can  use today, have a look at the Total Detox Procedure procedure.  Evaluate it here: I Need Help with This.


Water and Sports Drinks
This is flushing the system internally. Everyone knows that drinking lots of water is going to make you urinate more. Drinking several gallons of water can help to remove some toxins from your body, and help to dilute what you have taken in terms of drugs.

However, there could be trace amounts of those substances that do remain in the body for days, weeks, and even months. It depends on what it is and the volume -are you an occasional user, a chronic user, -only on the 4th of July?

It also depends upon other variables.  Body mass and metabolism levels vary from one person to the next.  A 120 pound person will store less metabolites for a shorter period than a 200 pound person.

If they test for creatinine, then you will likely have lower than normal levels of it after flushing. This is going to be hard to explain, as it is a highly probable indication that you have been trying to flush your system to clean up your urine.

Alternating water with sports drinks though, can be a good solution. It can help to clean up the urine and to pass toxins faster, all while helping you to keep decent enough creatinine levels.

Increase Creatinine
The body naturally produces creatinine, and you can also buy supplements at most health food stores. Increasing the amount of creatinine in your urine may help with diluting various types of drugs in the system. For the best results, you do need to start about 48 hours before the test will take place. If you have a shorter window of time, it can be more difficult to do successfully. Keep in mind that many tests for drugs also will identify the level of creatinine present.

If it is spiking off the charts, it can be a red flag. However, you can always tell them that you are involved with using the supplement for a very strict diet and workout regiment. If you are in decent shape, this could be a believable story that will at least buy you some time before a second test is conducted.

    Sammie –

    Thanks for stopping by to visit.

    Laboratories used for screening urine are sophisticated enough to detect adulterants such as Visine.

    Kind regards,

    Dave J

    if you put visine in your urine will that dilute the pee enough for marijuana to get outtqa system

    Hi Kristin –

    I think you’ll be fine. (No guarantees, of course). I’d be interested in knowing if you had any problem with it, though.

    Thanks for visiting.

    Best regards,

    Hi! I just want to preface this by saying I’m a paranoid person, haha. But I don’t smoke weed or do any sort of drugs. I had a pre-employment drug test on Monday, which is no big deal — except that I was exposed to second hand pot smoke for about 40 minutes in an improperly ventilated car on the Saturday prior to my test — not even a full 48 hours before I had to take the test.

    I didn’t feel high or any different than normal, but I wonder if my urine sample will test positive all the same. I drank lots of water on the Sunday prior to the test. Do you think this would have been enough time to flush anything that might’ve been in my system out? Or would the amounts of THC exposure be so minimal it wouldn’t even matter?


  5. David Jerczak says:

    Erik –

    Be sure and let me know how you made out on that one. I’m curious too.

    Dave J

  6. Erik says:

    Hey man I smoked weed but only took 2 hints nd had a drug test two weeks and 2 days later. But I also lift weights and run a lot every day! I drink water not a lot but I do. I had the drug test and I was worried about failing it! So I peed a little and added a little water as well, should i be good?

    Jon F –

    As I wrote to Frank above, you, too, are dancing too close to the edge. No time to fool around.
    That, of course, depends upon how emotionally attached you are to the outcome.

    How high are the stakes?

    I would use the Drug Test Friend procedure (more info here:

    It is generally regarded as reliable.

    Thanks for visiting here and good luck to you.

    hi !!! plz help me. how to detox the meth in my urine. becouse my company rondom test will start on friday 8-29-14 thanks

    Denise –

    I wouldn’t read too much into it. I think they all go to a lab. And rthe results are not usually that quick.

    Your background check is another thing that takes time.

    Relax. Stay cool and stay out of trouble.

    My question is boh me n my friend went for a pre employment drug test…i last did a small bit of coke saturday nite, sunday morning and tested on thursday morning…she on the other hand smokes weed and got this stuff called palo azul to clean her system (she said she has used it before n passed) so she tested thursday also but she said her urine came out like water….the results were to b sent to the company within an hour, well she called today n they said they had not recieved hers so she called n found out hers was sent to a lab…what does that mean for her? N the company said they recieved mine but were still waiting for background check? Is this bad n thank u

  11. David Jerczak says:

    There are lots of variables, Jane. I can’t really answer your question.

    I always fall back on my stock answer -which is, how emotionally attached are you to the outcome?
    How high are the stakes? Is failure an option?

    The ‘Drug Test Friend’ procedure is considered reliable. It is not, of course, the only
    solution -but, if you are unsure…

    about your friends procedure, you might want to use it.

  12. Jane Fonda says:


    So I’m a recreational marijuana user (once or twice per day) and have a pre employment drug screen in a few days. I am naturally pretty healthy (about 5’6″ 130 lbs.) and workout everyday. For the past few days to detox I have taken Niacin, as well as Cranberry pills and been drinking 100-120 oz’s of water a day. My friend used a detox drink one hour before his drug test (a school athletic drug test) and passed (mind you, he had just smoked a blunt lol). I bought the same detox and plan on using it before. What do you think my chances are of passing and do you have any suggestions?


  13. David Jerczak says:

    Pat –

    A most unfortunate turn of events. You are always free to dispute the findings which should result in a repeat test.

    One requirement of every pee test I ever took was to list any and all prescription meds that I may have been taking.

    To ‘not list’ them up front may have been construed as some evasive action on your part -causing you to catch the evil eye.

    Dave J
    Thanks for visiting. I hope that helps.

  14. Patty says:

    I took a court ordered drug test (urine) last week. I had already told the social worker I would test pos for cannabis yet the test came back as altered, no cannabis found but they found all my prescription meds. They blamed me for altering yet I did nothing to alter it. As I said before I told them I would test pos for the cannabis so why would I try to do something to make it come out any different. I’m wondering if anyone else has had this happen to them? And why would this have even happened when I did nothing but take the test. No dilution, no altering in any way at all?

  15. David Jerczak says:

    Hey Mike –

    To answer your question -I don’t know. It’s hard to tell as there are many variables.
    I was subject to random testing since 1992 until 2011 when I let go of that line of work.
    I never saw a drug screening that would not permit you to challenge the result -usually in the form of a retest.
    Sometimes the sample was ‘split’ at the time of collection and half was frozen. That wouldn’t do you any good.

    You would want a re-test.

    If it comes to that, I would assume an attitude of righteous indignation.
    Be calm and cordial throughout; gentle but firm (in your attitude of R.I.).

    Remember, if you are truly clean, they are wrong and you are right.
    Handle it politely and calmly and I don’t think you’ll have a problem.

    i hope that helps.

  16. Mike says:

    Thanks for the reply Dave. My concern is not that I’m clean, it’s I might come up “negative diluted” which I read some companies take as a failure of a drug test. Not sure if company I am apply for allows retest. So given the amount of water I drank listed in my last 2 posts do you think my Creatine and gravity levels wil pass the Specimen validity testing (SVT)? Thanks.

  17. David Jerczak says:

    Hey Mike –

    Relax. If you’re clean, you’re clean. If they don’t believe you, let them test you again.
    You have nothing to hide. You’ll be OK.

    Thanks for visiting us here.

    Dave J

  18. Mike says:

    I am clean have not done anything for 3 months. Concern is my sample will be negative diluted. Bladder shy so I drank 2 liters of water starting at 9:30am. Voided 4 times before I took the actual urine test at 1:30pm. Urine was not clear in sample bottle but it was light light yellow for sure. Think I will be ok? Not sure if possible employer will allow retest for negative diluted. Cannot access Employee handbook yet. Please advise.

  19. David Jerczak says:

    I’m not sure, Alicia, to be frank. (Not sure it matters).

    If tampering with the urine sample is evident, it is often an automatic failure.
    You might find instances where a retest will be required.

    Dave J

  20. alicia says:

    Can a lab tell the difference between hydrocodone and oxycodone? Or are they both categorized as just opiates. If they can tell, is it common for them to figure out which was taken? Also, if urine is diluted is it an automatic fail or will there be a retest?

  21. David Jerczak says:

    J. –

    Diluting doesn’t work because the labs know it’s diluted. it will be termed ‘inconclusive’ -which is as good as failing.
    They will want you to retest, most likely.

    Dave J

  22. David Jerczak says:

    Bob –

    The labs are much too sophisticated these days. Won’t work.

    Thanks for the note.
    Dave J

  23. J. Smith says:

    If a person was using Oxycodone, approximately 60-90 mg on the day they use, and they use almost every other day (3, sometimes 4 days/ week), could they pass a drug test within 24 hrs of using by diluting?? It would be a home drug test and it wouldn’t matter if the urine is clear or not. I would think you could pass a drug test for anything by doing this since some places fail you if your urine is clear when tested, but I don’t know and that’s why I’m asking. If the person drank water all day and was urinating clear before the test, and continued to drink until tested, would a home test be able to pick up on anything in the sample??

  24. Connor says:

    What do you think about visine diluting urine tests bob

  25. Owen says:

    I’ll take my chances with this method and hopefully everything works out. I still have 4 days until the test, so I’ll start drinking water and sports drinks from today and I’ll get the creatine supplement tomorrow, so I can increase the creatinine level. I’m pretty fit and I lift weight 3 times a week, so I can use that as an excuse for my high level of creatinine if they ask. If might just get a pass if I do this right. I’ll thank the author a ton if everything works out.

  26. David Jerczak says:

    Hey max –

    Sorry to hear you are in that position. It sounds like you’re at peace with it.
    Good luck and thanks for visiting.

    Dave J

  27. Max says:

    Frankly I have nothing to lose by cheating the test. If I get caught, then I get fired. If I get tested normally, then I get fired for getting tested positive. I might as well give diluting the urine a shot. I just gotta hope that they don’t do the balancing test and test my luck. I don’t want to lose this job, but if I do it’s not gonna be the end of the world either.

  28. David Jerczak says:

    As we’ve said before, Alurina, the labs have gotten sophisticated.
    We’d be interested to know if you pass this one. Please let us know.

    Dave J

  29. Alurena says:

    It wasn’t alot of urine and about a pill bottle size of amount of urine the nasal spray was a good amount squeezed in temper was good and color was light yellow but yellow and there didn’t seem to be and issue with the sample they then placed in 2 other container. Im just not sure I can’t believe they did this drip right before I got off work and then transported me by taxi there and back to the job site should I prepare for the worse or maybe a false positive?

  30. Alurena says:

    Hi i was force into a drug test to day by my job and all i could do is add a bit of pee and water and nasal spray was wondering would that dilute my urine enough to pass

  31. Luke says:

    My company invests in nothing employee related, so hopefully their drug testing will be as antiquated as I’m hoping. I’ve read a ton here about drug tests and how to beat them. I believe I have a good shot, especially because I work for a crap company. I’ll either use this method, the water and sports drink, or I may go with the synthetic urine. I haven’t decided on which, but as far cheating the test, that I’m sure I’m doing. It’s like a flip of a coin, but that’s what will decide how my life will unfold in the year 2013. Wish me luck everyone.

  32. David Jerczak says:

    Thanks for sharing, Bob. Others have tried vinegar with varying success, as you are probably aware.

    I think the flushing method works with the most consistency. You might want to try that sometime.

  33. Bob F says:

    Hi –

    I used Gatorade with a little vinegar mixed in. I drank two quarts each day for three days.

    I got by the urine test but I don’t know why. Maybe it was the vinegar. Or, the combination.

    Either way, I’m free. For now.
