Synthetic Urine: All You Need to Know Before The Urine Test

Here’s a common situation: you must pass a drug test tomorrow, but you’ve been using cannabis products for recreational purposes – synthetic urine may be the answer. For some people, it’s a secret concoction that may help you save the day. Synthetic urine for drug tests mirrors the composition of natural human urine.

Is it true that some technologies can help labs detect synthetic urine in 2023? You probably have more questions than answers. So, let’s unravel everything about synthetic urine. Know its ingredients, how to use it, and some trusted synthetic urine products.

Synthetic Urine: Detailed Guide

What Is Synthetic Urine?

Synthetic urine is laboratory-made with the same composition and physical properties as natural urine. Some people use it for testing, props, and medical research. Today, some also use it as a substitute for real urine during a drug test.

Production requires precise proportions and stringent quality control measures for reliable and consistent results. Commercially, several online stores sell it in pre-packed kits or solutions that the user can discretely bring to the drug testing site. However, its use raises legal concerns about deceiving drug test results. Consequences and penalties may vary depending on different states.

Composition and Ingredients of Synthetic Urine

Synthetic urine consists of water, urea, creatinine, pH adjusters, colorants, and odor additives to mimic natural urine’s composition, odor, and physical appearance.

The pre-mixed formula uses water as the base, providing the synthetic urine’s liquid component. Urea, a waste product, contributes to the authenticity of synthetic urine. Creatinine is also a waste product that replicates the levels found in natural urine.

On the other hand, pH adjusters ensure that the synthetic urine has a similar pH range. Finally, colorants and color additives match the appearance and smell of human urine. These ingredients, when combined, give you a solution on how to pass a supervised drug test with fake urine.

How to Prepare for a Test Using Synthetic Urine?

You probably feel nervous and desperate because of your upcoming urine drug test tomorrow. The problem is that you’ve been using weed for medicinal or recreational purposes. There’s no time to detox, so you have no choice but to use synthetic urine to get a negative result.

One of the most important steps to follow is to heat the synthetic urine to the right temperature. The standard temperature is between 90℉ and 100℉, which corresponds to 32℃ and 38℃, respectively. You can use a heating pad or a microwave to attain the correct temperature, but always check the instructions for the preferred heating method.

Once you have heated the urine, make sure to conceal it in a place that is secret and secure. Most synthetic urine kits come with prosthetic genitals and belts that enable the wearer to safely hide the urine under their clothing.

  • Rubber band, as an option – Some people use a rubber band to hold the hose of the fake urine below the penis or above the vulva.
  • Strap it to the leg or thigh – A tight strap can hold a bottle of fake urine, but you must also strap hand warmers to maintain its temperature.
  • Conceal it underwear – Stash the sample and tape it so it won’t move in the groin area.

Regardless of which method you’ll use, make sure to practice. This way, you can mirror everything and ensure it works out.

The Synthetic Urine FAQ

Here are more common questions about synthetic urine.

Can synthetic urine be detected during a drug test?

Yes, if used correctly. Synthetic urine is commonly used by people who need to pass a mandatory urine drug screening. Although fake urine can look similar to real urine, drug testing facilities utilize various detection methods to distinguish between the two. The most common detection method is the presence of uric acid, the right pH balance, and specific gravity, which are only found in human urine. We recommend choosing a synthetic urine brand that has the proper ingredients and qualities to increase your chances of passing the test.

How to keep urine warm for the urine test?

Keeping the synthetic urine at body temperature is crucial for passing a drug test successfully. Most synthetic urine kits come with a heating pad that can be attached to the bladder or bottle for easy heating. There are some more options and details described in our article.

Is it possible to make synthetic urine (DIY)?

Technically, yes. But, attempting to make synthetic urine at home is difficult and not recommended. The required ingredients are hard to come by, and replicating the chemical makeup of actual urine is even more challenging. Homemade synthetic urine may not have the right pH balance or specific gravity, increasing the likelihood that drug tests will detect it.

Is there any female synthetic urine kit or is there any unisex synthetic urine available?

Synthetic urine is usually unisex. Some brands include an adjustable belt that can fit comfortably and discreetly under clothes. Female users may need to find a kit that comes with an extension tube to ensure easy use during the drug test. It is essential to follow the manufacturer’s instructions carefully to avoid detection by the lab technician.

Does Walmart or Walgreens sell synthetic urine?

Synthetic urine is not sold at Walmart or Walgreens due to their listing policies. In some states, selling or buying synthetic urine is illegal.

How many states currently have banned the use or sale of fake urine?

In an article published by the American Addiction Centers, at least 18 states are banning the use or sale of any fake pee test kit and other related products. It includes Arkansas, Louisiana, New Hampshire, and Oklahoma, to name a few.

The legality of fake urine products varies from one state to another. Some states continue to sell it, but not for tampering with drug tests. However, some THC detox products are acceptable in most states.

Does synthetic urine work for LabCorp urine tests?

Yes, it is possible to pass LabCorp urine tests with certain synthetic urine brands. However, it is crucial to select a trustworthy and dependable brand (some of them we have mentioned in this article) to ensure accurate and reliable results.


Synthetic urine is a substitute for real urine in various scenarios, primarily for passing drug tests for people with no other option or time to detox. It replicates the composition and characteristics of natural urine, ensuring a realistic sample during testing.

However, it is essential to approach synthetic urine responsibly, considering its ethical and legal implications. Engaging in deceptive practices or attempting to manipulate the results of a drug test comes with serious consequences. To avoid legal matters, it’s better to refuse a same-day drug test and explain a valid reason why you are using marijuana products.
