Xanax stays in the blood for several days given the long half life. Depends on dose taken how long it stays in the blood but may take longer than someone who abuses the drug and takes higher than normal doses.


Xanax can be detected in hair up to 90 days after drug first taken. Accuracy of test depends on a few factors such as length of person’s hair when testing,color of hair or whether it has been chemically treated or not.


Traces of Xanax can be found in urine for a week, up to six weeks even, after medication last taken. People who abuse Xanax will have a harder time clearing the drug from their system even after stopping due to this reason.


Addiction to Xanax happens because it is a habit-forming drug which is addictive. People can develop tolerance fairly quickly when taking the drug everyday. Higher amounts of the drug are thus needed to get the same result. Even without addiction, a person using Xanax may also experience withdrawal symptoms when cutting down doses or stopping Xanax. If a person is addicted, cravings will occur even after it is out the system. It is the body’s way of processing the drug and the brain is also impacted as well.
