If you’ve recently consumed drugs and have an upcoming supervised drug test, you’re probably looking for a reliable way to pass. After all, you’ll have a supervisor who could easily work out that you’re tampering with the sample. While I can’t guarantee you won’t get in trouble, I’ll give you my best advice on how to pass your urine test even if you’re not drug-free.

Why It’s Harder for Females to Pass a Drug Test?A female patient consulting in a doctor's office

Females face some additional challenges:

  • You can’t hide your kit or fake urine sample as well as males.
  • You’re more likely to experience anxiety[1] or show signs of nervousness.

That’s why I’ll focus on kits for females and give advice tailored for the gentler sex. But, if you’re a man, you can still extract some valuable information from this article. You just need to adapt my advice to your sex.

Supervised Drug Test: Monitored vs Directly Observed Collection

There are two subtypes of supervised drug tests:

  1. Monitored drug test
  2. Directly observed drug test

To pass a supervised drug test, you need to know the differences between the two and prepare accordingly.

1. Monitored Collection

During a monitored collection, the supervisor:

  • Walks the donor to the restroom and secures the room so that no one else can enter
  • Listens for the signs of tampering
  • Is forbidden from watching the donor produce the sample

That last bit makes the biggest difference between monitored and directly observed collection. You may want to use it to your advantage. In case you catch your supervisor peeking, you can refuse to take the test without any consequences.

2. Directly Observed CollectionA patient being interviewed by a medical professional before a drug test

If you’re under direct observation, tampering with your urine will be extremely tricky. The supervisor accompanies the donor inside the stall and must watch the urine go from his body to the container.

But not all is bad. If this is your first time taking a drug test, you can’t undergo direct observation.

In fact, direct observation is only allowed if:

  1. There’s evidence that you’ve tampered with the sample (e.g. the supervisor catches you in the act, your pee looks suspicious)
  2. You previously tested positive or have a track record of altering test results

So, even if you raise suspicions during your drug test, your supervisors are forbidden from directly observing you until they have evidence. Also, note that if you’re a female, you can only be observed by another female according to the law.

Urine Substitution

The only sure-fire way to pass a urine drug test is to use substitute urine.

This can be done by using:

  • synthetic urine
  • someone else’s urine
  • your own clean urine

We’ll walk you through all options. But before we do, know that using substitute urine is illegal. I’d still advise you to use it if you need to ensure you pass a supervised drug test because all the other options are less reliable.

1. Synthetic or Fake UrineSynthetic urine pouring out from a bottle to a small container

Synthetic urine is artificial urine created in a lab. It looks like real human urine and contains the same ingredients.

Well, at least it should. Here’s the thing: the quality of synthetic urine depends on the manufacturer.

If you go for the cheaper option, it probably won’t be as convincing as it should be. Urine that’s likely to pass as the “real thing” is balanced for specific gravity and pH and contains the following ingredients:

  • Urea
  • Creatinine
  • Uric acid

You can buy synthetic urine in online stores or even some pharmacies.

2. Another Person’s or Your Own Urine

Perhaps the best and cheapest option for passing urine tests is to use a friend’s or your own urine. This way, you’ll know for sure that it will at least look human and contain normal “ingredients”. But before you do, you may want to double-check that the urine doesn’t contain THC or traces of other drugs.

Natural DetoxA doctor comforting a patient

Natural detox is legal but doesn’t offer a quick fix. It will take you a lot more time to remove THC or traces of other drugs from your system compared to other methods.

The natural detox includes:

  • Drinking lots of water
  • Exercising
  • Eating food with little to no salt and sugar
  • Taking activated charcoal, cranberry pills, or a detox drink

You’ll need to do all of the above on a regular basis, so you may have to change your lifestyle. The rewards for your dedication may be worth it, though.

“These detoxifier drinks, exercising, and drinking a lot of water prior to a test can flush [THC] out of the system. It’s a two-layer protection system. The detoxifiers will help [remove] the THC out of the fat cells and they also supply something in case it didn’t get all of it.” – Barry Cooper, former drug agent [2]   

    So, if you do have the time to make this method work, it could be extremely effective.

Can I Use Flushing?

Some say that flushing is the best method of ridding your body of THC and some other drugs. Like natural detox, flushing is completely legal.

It’s also quick but less reliable than synthetic urine because it may not work as effectively as it should. Flushing comes down to drinking lots of water and/or taking niacin flush pills.

Diluting your urine with water may alter its appearance. To ensure it still looks normal, you need to take:

  • Vitamin B to restore the natural color
  • Electrolyte powder to keep your gravity level within the normal range
  • Creatinine to increase it to normal levels

How to Hide Your Substitute UrineA doctor holding a urine sample while talking to her patient

1. Use a Special Device – Whizzinator

Whizzinator is a drug test kit that contains:

  • dried urine
  • syringe
  • heating pads
  • elastic belt
  • temperature strip

Before you complete your purchase, check if you’re buying a female kit. Male whizzinators have an artificial penis, which you definitely do not need.

Female whizzinators, on the other hand, have only a urine pouch that you can drain by removing the nozzle. Simply pour the clean urine from the kit into your cup and hand it in.

2. Tie It Around Your Body

The best way to make sure no one notices your substitute urine is to tie it around your body. Whizzinators have an elastic belt that serves this exact purpose.

If you don’t have a whizzinator, use duct tape or a belt to tie the urine sample around your body. Keep it well-hidden at all times.

How to Ensure You Don’t Get Caught

To pass a drug test without anyone noticing you tampered with the results, follow these rules:

  1. Hit the right temperature. Keep your urine at your body temperature, which is around 38°C (100°F). Synthetic urine and substitution kits usually come with warmers that keep them at the perfect temperature. Check out our article on how to keep urine warm for a drug test to learn more.
  2. Use a special device. Use Whizzinators or similar devices for discreet urine substitution.
  3. Practice at home. If this is your first time cheating on a urine drug test, you’ll be nervous. Take a few practice rounds at home to ease the tension.

What to Do If You Get Caught

You can only retake your supervised test at this point. Your report will state that you’ve tested positive or, at best, that you refused to take the test. Note that doing everything right at the collection site doesn’t guarantee that you’re out of trouble just yet because your urine still needs to pass the lab test.

Can I refuse to take the drug test?

Yes. No one can force you to undergo drug testing but refusing might have negative consequences, like not getting hired.

Can drinking water help?

Drinking water might help remove evidence of your drug use from your system, but there’s no guarantee.

Conclusion: Can You Pass a Supervised Drug Test?

Yes, you can pass a supervised drug test. It’s up to you how you’ll go about it.

Substitute urine might not be the best option for you if you’re an anxious person, while detox and flushing aren’t a reliable way to pass if you don’t have a lot of time on your hands.

Whatever you do, keep calm and don’t let your supervisors sense that you’re nervous. This may trigger alarm bells right from the start.
