alprazolam(xanax) drug test

How long is the detection time for benzos like xanax?

If I were to take just 4mg of xanax, could I pass a urine test in 4 days?? I havent done xanax in a week prior, and last time i only took 1 mg.

thanks for the help

 

erowid says 7-10 days for single use of valium, but didnt say about xanax. I assume theyre about the same, though. youll probably be good, but you might not be.

 

Xanax half life is 9-20 hours I believe. Valium is about 100 hours.
