It’s true; synthetic urine is an actual thing. In fact, the process of using fake pee to pass a drug test seems to be something that is growing in popularity. When you consume cannabis regularly, the last thing you want to do is rely on your own urine to pass a drug test. But, in reality, drug tests aren’t just a problem for regular smokers. Even for first-time smokers, weed can be detected in the system for up to 8 days. It’s not easy to give an exact length of time that weed is present in the system, since this number will vary from person to person and is dependent on a number of factors. But naturally, drug testing will be more of an issue for regular smokers since the possibility of testing positive is higher.

Many marijuana consumers are turning to synthetic urine to pass urine drug tests. But it’s becoming harder to get away with because drug testing companies are quickly catching on to the practice. In addition to stricter supervision, which makes it harder to use fake urine, laboratories are now also able to test for this, meaning they have the ability to test if the urine isn’t from the human body.

The good news, however, is that it’s still very possible to pass your drug test with synthetic urine – you just need to know how to do it. That’s why we decided to compile this article, to give you everything you need to know about synthetic urine.

What is Synthetic Urine?

So let’s start with the basics, what exactly is synthetic urine? More commonly known as “fake pee,” synthetic urine is also known as laboratory urine and is a substance created to mimic the appearance, chemical properties and, most importantly, composition of human urine. All of the major components of natural urine can be found in synthetic urine, including (among other things) creatinine, uric acid, urea, ammonia, and sulfates. Even the pH level and specific gravity in “real” and synthetic urines are nearly identical.

Fake pee is available in a few common forms, including dried powders and pre-mixed solutions. Both of these forms can expire with time, so it’s a good idea to replace any unused kits that may have been lying around for a while.

So what is synthetic urine made of anyway? Basically, it’s a liquid that has been scientifically mixed to form a urine-like sample. Here are four main components to be considered:

  • Color – It goes without saying that “fake pee” cannot just like be any old liquid, and it certainly can’t just be any color. Thankfully, chemists have figured out how to make it look exactly like real urine. It’s nice usually a nice “warm” yellow-ish, and is anything but colorless.
  • Creatinine level – Chemists include minimal solutions in fake urine for it to be like that straight out of the body. This is because minimal creatinine levels can’t be a factor to make urinalysis positive.
  • Temperature – Chemists first check the temperature of actual urine, and then add chemicals for the liquid to appear authentic.
  • pH Level – This is measured from original urine, and certain components are then diluted to make it appear original. It’s then tested and improved in the mixture.

There’s no doubt that synthetic urine is the fastest and most effective way to pass a urine test. However, there is actually much skill and a decent amount of risk involved, since you would need to smuggle the fake pee into your test and/or switch the sample with your actual urine.

How to select the best synthetic urine to pass a drug test

If you’re concerned about cheating on a drug test with synthetic urine, we completely understand. Many artificial urines are unreliable, and while some could even be detected in drug tests, others just don’t work at all. That’s why it’s important you choose the right brand and a product that you know is legit.

The market is full of various brands of synthetic urine, though, which can of course make it difficult to select the ideal synthetic urine product. Here are a few key things to consider when browsing around for the best options:

  • Uric acid – Since normal urine contains uric acid, most labs will test for the presence of it when carrying out a drug test. This is why it is vital that you ensure that the product contains uric acid when you purchase synthetic urine. Always check the label of the product.
  • Trusted dealer – The increased demand for synthetic urine has caused a significant increase in counterfeit products — “fakes,” if you will (no pun intended). Always do your research and don’t fall into the trap of unscrupulous dealers. Only by the best (i.e. don’t be afraid to spend a few extra dollars) and check out the feedback that has been given by people who have used that specific brand.
  • Temperature – The temperature of urine is approximately 36-37C, or 95-100F. Thus, the synthetic urine must have a temperature that is very close to real urine. The best products come with a heating pad to keep the urine warm, and also a special strip that displays the current temperature.
  • Shelf life – Drug tests usually pop up unexpectedly, thus it is critical to make sure that your urine hasn’t expired if/when you are randomly informed to do the old “pee in a cup” routine. Synthetic urine has an expiry date, and therefore you should always ensure that you have an extra bottle with a long shelf-life nearby, or at the very least replace your urine periodically with a fresh one.

How to cheat on a drug test with synthetic urine

Now that we’ve covered the basics of synthetic urine and all that it entails from a chemical perspective, let’s take a look at how you can actually use it to pass a drug test.

Although different products and brands may have different processes, they generally all work on the same principle. So we will give you the low down from a general perspective. Many synthetic urine kits will come with heating pads to test the temperature, as well as belts for easy hiding around the waist.

Typically, cheating on a drug test with synthetic urine is quite an easy process, and if you have chosen a reputable product and carefully follow the instructions, you should be fine. On the day of use, shake the heating pad a few times and attach it to the belt’s bag. Next, close the clips and cut the tube to the length needed, then wrap the belt around your waist and ensure it’s covered by all your clothes. The temperature strip must be touching your skin, and the tube should be pointed towards the ground. You must attach it at least an hour before the test.

This last step is the trickiest, and the most critical. Once you have the pee cup (and hopefully some privacy), you can unfasten the clips and pour the fake pee into the required container or cup. And, you’re done! Obviously, this last step is dependent on you not having a ‘supervisor’ watching over your shoulder. If you do, it will obviously be a little more tricky, but generally it should be easy enough to pull off. It’ll likely get your heart racing though.

Having to take a urine test is no doubt inconvenient, but as you can see there is a way around it, and there’s no need to hold yourself back worrying about a drug test.

Powdered vs. Liquid synthetic urine

Synthetic urine is available on the market in both powder and liquid form. There has been much debate around both of these forms for awhile now, with many people wondering which is the better of the two.

We have explained the liquid form of synthetic urine, but what is powdered urine? Well, it smells, looks and behaves chemically as drug-free human urine does, and, you guessed it, comes in the form of powder. Rather than receiving an already diluted form of synthetic urine, though (as with the liquid form), you buy the powder and mix it with water prior to the drug screening. It’s also 100% natural human urine that has gone through mass dehydration, which makes it one of the easiest and most accurate ways of passing any drug test.

Actually, dehydrated urine is proven to be 100% successful because it is drug-free. The urine retains all its properties and is identical in nature to real urine, which produces accurate results in a calibrating machine. While mixing the urine with water can be a little tricky, you would want to be as accurate as possible, and every brand that sells powdered synthetic urine should provide you with an instruction manual along with your purchase.

A recent synthetic urine review in fact, found that the liquid form is better for a number of reasons. One of the most significant reasons for this finding was because it is already mixed and ready to go, unlike powdered urine which requires you to do it yourself. It could be a little risky doing it yourself, and sometimes it’s better to leave it to the professionals, right?

Other reasons to use synthetic urine used for?

So we’ve established that one of the most common reasons for using synthetic urine is to pass a drug test, but what else is it used for? Here are a few other things that people would use fake urine:

  • Animal repellent – Animal repellent is often used by garden enthusiasts to keep rodents out of their favorite plants. Synthetic urine works just as well as the real thing, and brings down the overall costs for gardeners.
  • Pranking your friends – This is the most entertaining reason to use synthetic urine, and I guess for people with a little extra time on their hands, might be a “fun” little prank to try and mastermind.
  • Education – Medical students all around the world are trained using synthetic urine. Typical training includes urinalysis tests and clinical experiments.
  • Cleaning agents testings – Fake urine is very popular among salesmen and marketers to demonstrate the effectiveness of various cleaning agents for carpets and furniture, such as odor removers and urine stain. Sounds gross, but it’s the truth.
  • Science – Synthetic urine is used for a variety of different scientific purposes, from preparing for Mars missions, to development of new urine tests for different diseases.

Final thoughts on synthetic urine

At the end of the day, it’s great to know that there is a solution to the dreaded drug testing that’s commonly found in the U.S. workplace and in many other environments all across the world. While there are other suggestions for passing drug tests, such as detoxing and “chugging water,” synthetic urine is certainly the most reliable and effective.

While it’s not always 100% accurate, most of the time (if used correctly) you will pass your urine test with flying colors. Always remember, though, to buy a well-known brand and make sure your sample is warm when you hand it over. If you follow all the rules to a “pee,” you will be set for success.

    Can you reheat synthetic urine once it’s already been heated?

    Can you reheat synthetic urine once it’s already been heated and put in urine belt or will twice heating fuck it up?

    Simply golden

    Also, the reason I had to use synthetic was because this was a last minute unexpected opp. and I only had one week to quit, haven’t smoked but was a heavy user and didn’t trust detox drinks although I bought two ultimate gold drinks just in case.

    New synthetic urine brand Simply Golden

    I just took a drug test yesterday with Simply Golden synthetic urine. There are NO REVIEWS online yet because it is fairly new, but I am worried they will test for synthetic. I’m awaiting results currently and in a panic because this a huge job opportunity for me. I followed the directions and it says it contains everything needed so I’m hoping for the best. Has anyone ever heard of this one? Everyone else says I should be just fine, but realistically they probably don’t have a clue

    Water will pass a piss test easy

    Yes water will clean your system but their is a trick i drank 6 12 oz bottles of water out side my POs office and pissed clean i also smoked a blunt before i went to take my piss test for probation in new Mexico and i passed i didnt pee prior to drinking or smoking that blunt i even told her i smoked a blunt outside. But the 6 bottles of water diluted my system enough to get below the 50 scale points given . so yes watwr works if you have good health and zero body fat like me. Your body fat is what matters when passing a drug test thc metabolizes in your fat cells.

    Questions about Agent X

    I used Mr. Green’s Agent X. It was $40. The guy at the shop said people were complaining about Quick Fix so I used Agent X. When I poured it into the sample cup it was about 98 degrees on the thermometer. I had it stored between my legs but the temp strip was NOT facing my skin/body BC I did not want to have a false read BC it took my skin temp. I am very worried. Do you have any feedback on Mr. Green’s Agent X and the success rate? Do you think my temp was still accurate even thought the strip was away from my skin?

        PASSING A DRUG TEST IS SUPER EASY… if you take the right steps

        Mayo Clinic lab results say single use marijuana is detectable up to a maximum of 3 days, moderate use 5-7 days, daily use 10-15 days and chronic heavy use is 30 plus days… essentially it depends on how often you smoke and your metabolism…

        Below are a few steps to speed up your metabolism…

        1. Eat a ketogenic diet; it forces the body to metabolize fat which is where THC is stored (ketosis state). This is in contrast to a glycosis state, where blood glucose (sugar) provides most of the energy.

        2. Drink at the very least eight 8-ounce glasses of water a day; this will help flush your system as well as assist you in maintaining a healthy metabolism.

        3. Drink green tea; like water, this will lower THC levels through its diuretic properties and make an individual urinate a lot which technically washes out the kidneys. Green tea can purify your blood and get everything moving on. Incorporate in your diet throughout the day for at least a week leading up to your drug screen.

        4. Exercise and hit the sauna, steam-room and or Jacuzzi; all of these will speed up your metabolic rate and remove THC from your system quicker.

        Lastly you could get a detox kit from someone like if you want some extra assurance of passing…

          Also, if the testing is something more rigorous like a GC/MS, you may well be out of luck as they are very sensitive and can pick up very minute amounts of anything and everything in your system. If it’s just a pee strip, you may be better off. Some jobs also do hair tests. If you walk in blind not knowing what test you will get and you prepare for a piss test, but get a hair test, you’re also out of luck. To be honest, just quit smoking for a month or two before you start applying. I’ve had two instances where synthetic urine did NOT work for me. I ended up having to retest more than once which ended up costing a fair amount of money compared to just quitting for a while. Just saying, it’s very possible. If you really need the job and money, don’t risk it by being an idiot.

        2. Chris

          Burning fat close to a test is the last thing you’d want to do since THC can be stored there. Burning it could release more of it back into your system. Not advised if you have a fair amount of body fat and were a heavy or regular smoker.

          this article isnt about abstaing from weed … its about fake pee focus

        4. Nicolaj

          You’re passing on rumors that aren’t true friend. There’s no evidence that drinking more water will flush anything out faster. – Scientists has been discussing and researching this for many years.

          Green Tea won’t help either.
          Even those drinks you can buy to supposedly flush your system, don’t work.
          In the old days you could drink a lot of water, and your pee would become to thin to test positive.
          But scientists are way to clever these days. They will detect it even in the thinnest urine.
          And those pee sticks will just say “invalid” if the urine is to thin or tempered with.

          Single time use can be detected for up to 13 days.
          Regular use up to 45 days.
          And heavy users have reported testing positive for up to 85 days.
