How To Pass A Drug Test

For the past two decades, urine tests have become more and more popular around the world as companies put new emphasis on having drug-free environments. From governmental organizations like the Department of Transportation in the United States, to regular companies both large and small, the urinalysis is the go-to method for drug testing.

The Essentials

The urine drug test is a two-step process - the first step is getting the sample and the second one is testing it in for a certain substances. First check is usually done with EMIT assay dip strip test just by dipping it into the sample cup. In case of a positive result, the second confirmatory test using a different methodology called Gas Chromatography - Mass Spectrometry is done in an accredited lab.

Enzyme Multiplied Immunoassay Technique (EMIT) was introduced first in 1973 and is widely used nowadays for detection of drugs and proteins in urine. The process involves combining a sample suspected of containing certain drug with the enzyme substrate and concentration of antibodies. After waiting short time for binding, the rate of colour is measured and the concentration of drug is determined by comparing it with the rates produced by the previously tested known concentrations of the same drug.

If the result is positive, the GC-MS test is done to identify trace elements and byproducts (metabolites) of drugs with help of special laboratory equipment to prevent any sort of mistakes and prove the presence of illicit substances in the sample for sure.

Another important test is the adulteration check, which is done to determine if the specimen is genuine and has not been faked, diluted, substituted or had drug traces in the urine masked in any other way. There are several things tested in an adulteration test, including:

1. The level of creatinine in the sample. If a person attempts to drink an excessive amount of water or uses various diuretic products and teas to flush his urine, he will have lower creatinine as compared to normal level of about 15-20 mg of human body mass.
2. Specific Gravity. This is another sign of dilution of the urine as well as any other tampering. Considering that the normal level should be between 1.003 and 1.030, any deviation from this range will be the evidence of cheating attempts.
3. PH. Normal pH is going to be between 4.0 and 9.0, so if the sample has been altered in any way, that number will be outside of the given range.
4. Glutaraldehyde. Many urine masking agents sold to beat drug tests contain glutaraldehyde, which is not found in human urine naturally and its presence can be a sign of an attempt to beat a drug test.
5. Nitrate. Also not found naturally in human urine testify the possible attempt to cheat the drug test.
6. Uric Acid. The absence of uric acid proves that fake pee was used to substitute the original sample.

There are dozens of drugs that might be tested for with urine tests but the most common are marijuana, cocaine, methamphetamine and various opiates. All of them have different detection times, for example traces of marijuana usually stay in urine during one week (in rare cases up to month); cocaine is detectable during 2-3 days; meth 4-6 days; heroin, morphine and opium 2-4 days; LSD just one day etc. Exact detection times vary considerably depending on personal metabolism and quantity of consumed substance.

There are two known methods to pass a urine test for marijuana as well as for any other drug for those who used it but want to get negative result.

1. Urine Substition

The most common way is to substitute your specimen with clean one, and the cheapest and easiest substitution is to get the urine of someone else. The problem with this method is that it can be hard to find person who has clean pee and ready to give it to you. And even if you do find someone, you need to receive a sample almost immediately, because if you wait too long, even a few hours, the urine will foam, change color, odor and consistency as well as temperature, which is a tell-tale sign that it has been taken long time before test.

Luckily we have more usable option, which is growing in popularity and it is synthetic urine. This artificial substance is used by testing labs as a means of calibration of urine testing equipment, since the machines cannot be calibrated by human urine because each person’s urine is different and they need some basic sample. Comparing with real urine, fake pee is a much better choice for laboratory needs, as it has long shelf life, does not foam, does not stink and has permanent consistency.

In order to pass the drug test with synthetic urine, you need to do a few things. First of all, make sure your product contains uric acid, as this is something that labs are now testing for because of the rise of using artificial urine for cheating. If your sample does not have uric acid, the test is going to come back as a fail because of possible fraud. The second thing to do is to heat your specimen in a microwave and attach it to your body to keep it close to human body temperature. Most synthetic urine kits have special rubber band, heating pad and thermometer for this purpose. The next step is to pour the liquid into the testing cup, what may be daunting task, in case you're supervised, but special devices like Whizzinator will help you solve this problem.

All in all, it can be hard to get away with using this, depending on circumstances, but it is one’s best bet for passing a urine test when using the substitution method. Synthetic urine can be purchased online.

2. Urine Cleansing

Urine cleansing is another proven method to beat a drug test and it requires accurate following few important steps.

The first thing you should do in case your test is not sudden, but pre-announced few days before is stop taking any drugs and toxic products immediately. Unless you are habitual user, most drugs will pass from your system within a few days in natural way.

The next step is cleansing your kidneys and bladder by drinking a lot of fluids. Drinking is a great way to flush your system not only because it is passing clean liquids through your body cells, but it is also going to cause you to urinate on a regular basis, thus washing out more toxins from your body and leaves your kidneys and urine clean as a whistle. Frequent urinating makes your urine look pale, so it is recommended to take B vitamins before test to color it yellow.

Aspirin is useful for first check test, as it interferes with EMIT assay and decreases its signals. Take about 1.3g 4 hours before deadline.

You can also take special detox drinks that will cleanse your body of all toxins. The great thing about these products is that they not only contain diuretics, which will help you urinate frequently, but also include all required vitamins and minerals that make your pee yellow and are beneficial for overall health. These drinks are very effective and available online in a wide range.



Even after thorough body cleansing, you should never use the urine from your first urination of the day, because it is loaded with toxins that have accumulated over the course of a night. Urinate at least once before going to drug test and if you followed all instructions carefully, you will pass it easily.
