ANOTHER ANSWER

XANAX (alprazolam) HAS a "duration of action" of up to 6 hours. If you want to know how long after you take it can it be DETECTED, that's different. Most benzodiazapines, when taken on a regular basis, can be detected in the urine from 24 hours to 72 hours. If you are concerned about failing a urine test, give yourself a good 3-4 days to be extra safe,,(if it is really important to you). Also, if you have a valid prescription for Xanax, you would not be considered a "fail".

Answer

YOU ARE WRONG. Xanax, like all other benzodiazapines, is stored in the liver. Your liver then realeases it through the same way it realeases stored sugar. This means that, for a chronic user with a low metabolism, it can take up 6 WEEKS before it is unditectible through the urine. One days use will be out in about 3 days, however, if you have used everyday for more than a month you had better give yourself another month off the drug before your GOD-CURSED drug test
