I took 8 1.0 mg (blue footballs) on a Friday night and then had to take a drug test the following Wednesday. I have took them before and passed tests a few days later but there was a time when I took some and it stayed in my system for about 6 days with the levels being well over the accepted levels. I used a detox drink the day I took the test. Followed the directions and took the test about 4 hours later and now I am really worried I didn't pass it... PLEASE Need some useful information PLEASE!!!

How long does Xanax stay in your system?
7 Nov 2011
The mean plasma elimination half-life of Xanax is reported to be 11.2 hours. The full range is from 6.3 to 26.9 hours in healthy adults.
For a drug to be totally eliminated from your system it takes 5.5 times the half life.
If we take the maximum time of 26.9 hours times 5.5, it will be in your system for approximately 148 hours i.e. 6 days, after your final dose.
If you need to pass a drug test the best advice I can give is don't take the drug!
Detox drinks will not work - abstinence is the best policy!
