Benzodiazepines are used to treat anxiety, muscle spasms, seizures, and sleep disorders by depressing the central nervous system. Though very effective, they can also be seriously addictive and are often abused recreationally.
Xanax calms the nerves and produces a feeling of relaxation at standard doses, which come in pill form. If taken at high doses, especially if crushed and snorted or mixed into a solution for injection, it can create a euphoric high.
How Quickly Does Xanax Leave the Body?
This spike in illegal abuse of Xanax led to the creation of tests to detect the drug in people’s bodily fluids and tissues.
On average, Xanax has an elimination half-life of about 11 hours (though the range is from about 6-27 hours—sometimes higher in obese patients). This means that it takes a healthy person’s body this amount of time to get rid of half of a dose of the drug.
- Metabolism speed
- Height and weight
- Body fat content
- Health of the liver and/or kidneys
- Amount of the drug taken
- How long the drug has been used
The tests used to detect Xanax in a person’s system are blood tests, urine tests, saliva swabs, and hair follicle analysis. Urine tests are the most commonly used, but the length of time that Xanax stays in this bodily fluid depends largely on how heavy abuse of the drug has been. For occasional users, a urine test will usually not work past 4 days, but in heavy users, it can detect the substance for up to a week.
