Benzos are not among the big 5 recreational drugs usually tested-for by PO's. If you are clean for MJ, Coke, Meth, Opiates and PCP on the quick test, they may not even ship your specimin to an expensive lab for analysis. If you have legit Rx for benzo's, it's not an issue either way.

Only way we would have ever tested for benzos, when I was a PO would be if illegal possession/sales of benzo's was the charge that got you on probation in the first place. Or a DUI with benzos involved. Hope this helps.
