I take valium sometimes to help me relax when on a cycle & training hard.We have regular random piss tests at my job.I was told by a co -worker that one of the guys piss tests came up positive for Barbitiuates from taking a valium the night before.Im not sure if this is really true or not but since of course I do not have a script for them I am a little worried.Im wondering if anyone knows if this is true & if so what are the detection times?
