In rare instances valerian root has been reported to show up as false positive for benzodiazapine on drug tests.However, any false positive would be sent for GC/MS confirmation, and this would clarify that it is not a benzo.

What is GC/MS confirmation?
Thanks for the follow-up.
GC/MS is gas chromatography/mass spectrometry, the testing methodology uses to confirm presumptive positive drug screen specimens.
GC/MS provides identification of the molecule(s) based on characteristic fragmentation patterns at specific retention times.
It is more specific test for benzos and that will definitely come back negative for benzos if he had not taken any.
