How Long Do Benzos Stay in Urine


Xanax. Valium. Klonopin. Halcion. These are just some of the names for benzodiazepines, otherwise known as benzos.

Each one of these variations comes in the form of an over-the-counter prescription. People commonly abuse benzos for their sedative properties, which is why they also have the nickname “the date rape drug.”

If you have any of these substances present in your body and are required to take a drug urine test, laboratory technicians will flag your sample if they find significant levels of benzos in the search parameters. They will flag your results only if they find substantial levels of benzos.

Companies and organizations use drug tests to mitigate risk. They want to make sure people are not abusing drugs, whether that be benzos or barbiturates [1]. It keeps the business running efficiently, reduces legal costs, and maintains a healthy bottom line. If you are curious about benzos showing up on drug testing, here is everything you need to know about the process.

What Are Benzos?

Benzodiazepines are synthetic drugs which are used to treat all kinds of depression. The benzos achieve the desired effect by altering chemicals in the brain. Specifically, benzos target gamma-aminobutyric acid (GABA) [2], which is a neurotransmitter.

GABA works to inhibit channels in the brain associated with anxiety or seizures. When GABA isn’t working to its full potential, an individual may feel a crushing sense of anxiety or chronic stress. The patient can take benzos to improve the inhibition effect, which is similar to the way someone may feel more carefree after drinking alcohol.

The excessive consumption of benzos can lead to a relaxing, euphoric, or “high” feeling, which is why they are so popular. Benzos are incredibly addictive, though, and medical professionals do not recommend taking these powerful drugs for more than four weeks at a time. Often, medical professionals prescribe benzos paired with antidepressants and antipsychotics [3] as a form of treatment.


How Long Do Benzos Stay in Your System?

The length of time that benzos can stay in your system depends entirely on the type of drug actions that occur. There are three types which interact differently: short, intermediate, and long. These categories reflect the drug’s half-life and how quickly the body takes to process and dispose of the drug.

Each of these three types is designed to target different conditions. They also come with unique side effects and detection periods.

  • Short-acting benzos, like Halcion and Versed, can lead to amnesia and disorientation, for example. In general, urine tests can detect short-acting benzos for up to two days.
  • The intermediate varieties, like Xanax, Rohypnol, and Klonopin, linger in the urine stream for up to five days.
  • Conversely, Valium, Librium, and Dalmane, which are long-acting benzos, can create a sedative and hazy feeling. Long-acting benzos can be detected for up to ten days.


Again, these windows are meant more as guidelines than as reliable parameters on which to base your hopes and dreams of passing a urine drug test. The detection window also largely depends on factors such as body mass, age, metabolism, urine pH, frequency of usage, the quantity of dosage, and personal health. For instance, a frequent user who lives a sedentary lifestyle is much more likely to test positive than an athlete who took benzos once.

The healthier the lifestyle that someone leads, the shorter the time benzos can be expected to stay in the body.

While this article focuses on benzos drug test with urine, it is worth mentioning the staying power for blood, hair, and saliva tests, too. Blood is the most efficient process, for example, and will clear benzos out of your system in twenty-four hours or less. Saliva will show traces of benzos for up to two-and-a-half days, while the laboratories can detect benzos in hair for up to ninety days.

What Can Make You Test Positive for Benzos?

It is possible to have a false positive test for benzos depending on factors like your current medication. The most likely scenario for a false positive is if you took a selective serotonin reuptake inhibitor, sertraline, or a non-steroidal anti-inflammatory drug like oxaprozin [4].

Currently, researchers do not fully understand the mechanism behind how benzos work, especially in interaction with other drugs. Many experts suspect that the device exhibits similar features to the previously mentioned drugs. That is why there is a high chance for misdiagnosis during routine urine screening.

How to Beat a Urine Test for Benzos

The first step to beating a urine test is to stop taking benzos with immediate effect. Withdrawal can be unpleasant, though, and it will likely come with side effects like drowsiness, confusion, weakness, headaches, and panic attacks, among other things.

If you are going to detox, it is essential to allow your body a fighting chance to rest and recover. It is never easy to let go of drug dependency, especially after an extended period of use. Cleansing your system is the best way to pass the urine test, though, and minimizing your chemical dependency is the only way to get there.

Detoxing is best combined with a healthy diet and exercise. Taking the time to sweat it out every day leading up to the test can boost your metabolism and improve the rate at which your body processes the benzos. Similarly, switching to a low-sodium, sugar-free, and non-fatty diet will provide less storage room for benzos to linger.

Finally, if you find yourself in a tight spot with nowhere to turn, you can always use synthetic urine.

Quick Fix 6.2 is one of the most trusted brand names of synthetic urine on the market. This outstanding product is both effective and discreet—exactly what you need to prepare for an inconvenient urine test.
