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.2
Are Benzos Addictive?
Because of the calming effect, users may easily become attached to benzodiazepines and tend to use the drug for prolonged periods. As a result, developing a substance use disorder with them can occur.
Benzos Side Effects
If the drug causes an overreaction in your system, some negative effects may materialize. The side effects of benzos include:
There are other more severe side effects of benzos, such as memory problems, delirium and hallucination, negative behavioral patterns, and higher risks of substance use issues.
Similarly, when users want to stop benzodiazepines, there may be some withdrawal challenges such as anxiety, prolonged fatigue, sleep difficulty, seizures, panic and agitation, migraines, general body pain, dizziness, and more.
How Long Do Benzos Stay in Your System?
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.6
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
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.
Genetics
Age
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.
