Does Synthetic Urine Work For Drug Test?

Mostly, yes. Drug testing laboratories in the United States usually do not perform genetic tests on urine specimens. Standard laboratory equipment just checks sample for certain drugs and toxins and whether it has been diluted or adulterated. If you use synthetic urine, you can check its integrity just by buying drug adulteration test strips that can check specific gravity as well as pH and creatinine levels and other substances that labs check. If your urine sample passes standard integrity test and has temperature between 90°F and 100°F, you will pass drug test for sure.

But this answer is not complete. Now labs are informed about synthetic urine and they can perform an additional analysis on the sample if they have reasonable suspicion that it was used. Also, you should know that use of synthetic urine is a felony in some states.

Is It Legal To Use?

Firs of all, this question is about legality of drug testing. There is no the only opinion about it. Officially drug test became legal in 1986 when president Reagan signed the special executive order. But many lawyers consider it unconstitutional, because of 4th Amendment to the Constitution of the US that guarantees
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures

Fourth Amendment to the United States Constitution
Many federal and state courts in the US ruled drug testing unconstitutional. From this point of view using synthetic urine in drug test is protection of your privacy, guaranteed by Constitution. In most states you can buy synthetic urine and use it legally. As of 2015 it is officially prohibited in AR, NC, OK, MD, IL, VA, SC, KY, NJ, NE, TX, FL, PA.

Where It Is Used

Synthetic urine was designed for laboratory use. Organizations such as drug testing laboratories, institutions and researchers use it to calibrate their drug testing equipment. Staff checks the accuracy of equipment by testing urine samples that were intentionally mixed with some toxins or chemicals. They cannot use real human urine for several reasons: it smells bad, foams and must be kept frozen during shipping, as decays fast if not cooled. Also, before taking human sample, donor has to be checked thoroughly for drugs or diseases, that can spoil sample. Moreover, every human has its own body chemistry, so different people have different urine composition. That causes troubles for consistent researchers. Synthetic urine was created to avoid all these problems.

Now synthetic urine is used for next, sometimes specific, purposes:
  • Drug Testing
    Synthetic urine is a chemical compound that has characteristics that resemble the real human urine. The lab produced synthetic urine is used for the calibration of drug testing equipment. Unlike natural pee, the synthetic one can be shipped without refrigerating and can be heated up unlimited times. Also this product is used for substituting drug test sample with the help of whizzinator or urinator in order to protect privacy.

  • Industrial Use
    Except drug testing labs, diapers industry uses synthetic urine for testing diapers.

  • Urine Therapy
    SYNTHETIC URINE IS NOT RECOMMENDED FOR INTERNAL USE, but some people believe that urine has a curative power. Some cultures, for example Indian, have traditionally used it for a medicine purposes. But using a real urine is unpleasant for hygienic reasons, so some people use a synthetic product as an alternative substitute, as it has most substances the real pee has.

  • Fetish
    Another possible use is for fetish purposes. Fetish community uses synthetic urine instead of real because of health reasons. Real human urine can contain harmful impurities, but synthetic one is clear and looks real thus providing a healthy way to play.

  • Pranks
    Some people consider it to be funny when dousing friend’s bed or clothing with urine. The synthetic product can help to avoid problems with resentful people. Unlike real pee, the synthetic one is absolutely healthy and hygienic, and does not contain the nasty substances.

Chemical Composition

Human urine contains a lot of different organic and inorganic substances. All of the components are either products of cellular metabolism or have been derived directly from food that people eat. The normal ratio of organic to inorganic components is about 3.5/2.5, although usually it varies from subject to subject.

The main organic components are urea, creatinine and uric acid. The main substance is urea that contains about 95% of the nitrogen of urine, so usually it is not necessary to integrate uric acid into synthetic urine. The second important substance is creatinine, that is a hydrated form of creatine. Usually approximately normal level of creatinine is included in the synthetic urine.

The basic inorganic components are chlorides, sulfates, phosphates and ammonia. Sodium chloride is about a half of all inorganic substances. Normally, there is very little of ammonia in fresh pee, because of its toxicity. But eventually, if urine stands at room temperature for some hours, the level of ammonia grows because of the breakdown of urea by bacterial action. So, a small amount of ammonia may be included (but not necessarily) in the synthetic urine to simulate the ammonia present in not fresh human urine.

Synthetic urine must have a temperature about 90-100°F to be an acceptable specimen. Usual synthetic urine formulation has a specific gravity about 1.00-1.035, a pH about 4-9 and a total solids content about 1.5-6% by weight. It necessarily contains urea, creatinine and water, and optionally includes a uric acid, a buffer, such as a phosphate buffer, phosphorus, potassium, calcium and a source of sodium.

In one of the variations, the synthetic urine consists of approximately 60-90 mg/dl of urea and 37-300 mg/dl of creatinine (this is the usual levels in real human urine). Also it contains about 0.5 g/l of magnesium chloride, 0.25 g/l of calcium chloride, 0.85 g/l of ammonium diphosphate, 0.85 g/l of ammonium phosphate, 2 g/l of sodium sulfate and 2 g/l of potassium chloride.

Urea and creatinine have to be present in an appropriate range for a real human urine. Optional components can include an appropriate amounts of estrogen or testosterone and an appropriate coloring agent, like vitamin B12, beta carotene or yellow dyes to look like human urine.

The synthetic urine, that is created to calibrate the drug testing equipment, can contain a suitable amount of a drug substance, that equipment is intended to identify. Such mix helps to make sure that the equipment is functioning in the proper way. Mostly, this substance is Cannabis or its active component TetraHydroCannabinolic Acid. Sometimes this is Cocaine or its main metabolite Benzoylecgonine, opiates such as Morphine or Heroin, Amphetamine, PCP, Acetaldehyde, Ethanol etc. Sometimes such substances as Acetyl Salicylic Acid or Acetominophen can be mistaken for drug metabolites. To rule out this possibility they can be added to synthetic urine that is used for a negative control in drug test.

Synthetic urine can have not only normal concentration. Also, it can be in powdered and concentrated form. The concentrated product can have the form of a liquid or gel, and sometimes even paste, and can contain some carrier, for example a water-dissolvable pectin matrix. The concentrated and normal synthetic urines are usually stored separately from the heat activator, that is added only when needed to heat the compound to the required temperature. The powdered product sometimes can be mixed with the heat activator and sometimes can be provided separately. To save the storage space, a dried synthetic urine is frequently used and mixed with water to form a liqiud mix when needed.
