The Respiratory Therapy Pinning Ceremony is a time of great honor and dignity and a special occasion for our graduates and their family members. We ask that you refrain from talking, cheering, excessive movement, and using electronic devices during the ceremony.
Xanax is a relatively short-acting drug when compared to Valium. If you're an average-size person, you would expect Xanax to stay in your urine for 1-4 days after last use. To be safe, you should wait at least a week. Note that this is very dependent on how much and for how long you've been taking it.
Depending on the dosage, it can be detected up to  5 days after the last dose. A single 0.5mg dose may not be detectable after say 3 days. But urine tests look for metabolites of a drug. In the case of Xanax, the metabolite is Î±- hydroxyalprazolam, which has the same half-life as xanax itself. If you are taking an Extended-Release version of it, then it may be in a your system for a bit longer. (Other benzos like clonazepam or diazepam, can remain for up to 10 days in your system due to very long half-lives).
