How Can I Pass a Urine Drug Test?

Apart from not using drugs, there is no reliable shortcut to ensuring a negative urine drug test. A negative result depends on whether the drug or its metabolites are present at or above the test’s specified cut-off level.

What Does a Negative Drugs Test Mean?

A negative urine drug test generally means that the drug or its metabolites were not detected at or above the test’s specified cut-off level. A negative test could mean any of these things:

• You haven’t used the drug that is being tested for
• You may have used the drug being tested for, but your system has metabolised all trace of the drug
• You have taken the drug but the levels in your body are so low that they do not reach the cut-off level of the test

What Is Urine Sample Adulteration?

The most common form of drug testing carried out in the workplace is urine drug test. This involves testing a sample of urine from the donor which is then screened for the presence of one or more drugs.

It is possible for the test to be tampered with at this stage. This is known as “urine sample adulteration”.

Sample adulteration is usually achieved in three ways:

• Substitution – the donor’s urine sample is “swapped” for a clean sample of urine
• Dilution – the urine sample is diluted in an attempt to produce a false negative test result
• Addition – masking agents are added to the sample to interfere with the screening test and/or the substances being tested for

Drug-testing laboratories can carry out specimen-validity checks that may identify unusually dilute, substituted or adulterated urine samples.

Can I Beat a Drugs Test by Using a Masking Agent?

Masking agents are substances that are taken to try and interfere or change the results of a drugs test. Many products can be found for sale on the internet that claim to “cleanse” your system so that you will pass a drugs test. However, a lot of these products are unproven and cannot be relied upon to eliminate traces of drug use from your system.

Myths abound that various substances can mask or hide your drug use so that you will get a negative result. Aspirin, bleach, salt, vinegar, cranberry juice and goldenseal are just some of the substances suggested.

The Truth About Detox Drinks and Supplements

Detox drinks and supplements are often marketed with claims that they can “cleanse” your system before a drug test, but these products cannot be relied upon to remove drug metabolites from the body. Your liver and kidneys already play the central role in processing and eliminating substances from the body.

Some “detox” drinks may simply increase urination or dilute urine temporarily. This does not reliably remove drug metabolites and may instead produce an unusually dilute sample.

Instead of relying on unproven methods, allow your body time to eliminate drugs naturally and maintain normal hydration rather than deliberately consuming excessive amounts of water.

Can I Pass a Drugs Test by Drinking Lots of Water?

You may try to beat a drugs test by drinking lots of water, but this may not work. Drug-testing laboratories can carry out specimen-validity checks that may identify an unusually dilute urine sample. A dilute result does not automatically prove deliberate tampering.

Drinking excessive amounts of water can also be dangerous. Taking in more water than the kidneys can remove can contribute to hyponatraemia, where the sodium level in the blood becomes too low. Symptoms can include headache, nausea, confusion and, in severe cases, seizures.

Can I Swap Urine to Beat a Drugs Test?

Swapping your urine for another person’s is also unlikely to provide a reliable way of producing a negative result. Collection procedures vary, but testing programmes may use measures designed to identify substituted or tampered samples.

Depending on the testing programme, collection procedures may include controls around access to water, checks on the sample or collection area, hand washing, or other measures intended to protect the integrity of the specimen.

In the UK workplace, employers normally need an appropriate drug-testing policy and employee consent, and testing should be justified and applied fairly.

Is There a Guaranteed Way to Beat a Urine Drugs Test?

There is no reliable shortcut for ensuring a negative urine drug test. The safest approach is not to use drugs and to allow sufficient time for the drug and its metabolites to fall below the test’s detection threshold.

If you want to check whether drugs are detectable before an upcoming drugs test, you can test yourself at home. Urine drug tests are available for cannabis, cocaine, opiates and most other common drugs of abuse.
