What are Benzos?

Benzos are a class of drugs alongside alprazolam, diazepam, lorazepam, midazolam, and clonazepam. The popular drug Valium is a brand of diazepam.

Stress and anxiety often lead to an overstimulation of the brain, which in turn causes a lack of sleep and then more stress. Benzos lessen the activity of those neurons in the brain that activate anxiety and stress reactions to help calm the brain.

How Long Do Benzos Stay in Your System?

It can be difficult to understand how long benzos stay in the body. This section talks more about this concept, along with the difference between short and long acting benzos.

Half-Life of Benzos

There is no definite answer to how long benzos stay in your system. Benzodiazepine is a group of drugs, which means there is no definite period that the substance spends in the body since there are several drugs involved.

This also applies to the half-life of the drug, which is the period it takes for the substance to reduce itself by half in the body. Estimates place the half-life of benzos ranging anywhere from one to twelve hours.

However, the specific hours will be determined by the type of benzos a person consumes. There are two main types of Benzos:

Short-Acting Benzos

These have a briefer half-life and can leave the body quite quickly. Typically, the half-life of short-acting Benzos is between one and twenty hours. Examples of short-acting benzos include Midazolam, Alprazolam, Estazolam, and Lorazepam.

Long-Acting Benzos

These can persist in the body for lengthier periods. The half-life of longer-acting benzos can range from twenty-five hours to several days. Examples of long-acting benzos include Chlordiazepoxide, Quazepam, Flurazepam, and Diazepam.

Factors That Affect How Long Benzos Stay in Your System

The amount of time that benzos spend in the body differs depending on several factors, including critical body indicators.

Liver Functioning and Metabolism

The liver is the organ that cleanses the blood of any impurities or external substances. Its functions include filtering for drug substances and breaking them down. This breakdown is called our metabolism.

If the liver functions optimally, it will break down benzos faster, making it less likely to find traces of the drug in the body after some time.


The body systems of some people are better at processing and excreting substances than others. This ability to process substances better is often a result of their inherited capabilities and genetics. Since we do not have control over this, it’s not something that should be relied upon when looking into how long benzos stay in our systems.


Age is another element that one cannot control. The older a person gets, the less efficient their liver metabolizes substances. Benzos tend to stay longer elderly people than they do in younger generations.

Alcohol Use

Benzos and alcohol often don’t go together, as benzos are sometimes used to treat alcohol addiction. Both benzos and alcohol are substances that the liver needs to metabolize. Thus, consuming both will give the liver too much work to do. Never attempt mixing alcohol and benzodiazepines, as this will aggravate the side effects of Benzos use.


The heavier a person gets, the more metabolism the body has to go through. The result is that the liver and other organs involved in metabolism may get overwhelmed. As such, they may not perform as well at processing benzos.


Consumption of fluids such as water lets the body filter out wastes and substances. High intakes of water and other hydrating liquids may lead to a lower presence of drugs in the body.

General Health and Other Factors

Healthier bodies process drugs faster and wean themselves of the presence of substances easier. Lifestyle choices such as nutrition and exercise are also contributory factors.
