I part ways with you here. I abused alcohol BIG TIME, but have never abused prescription drugs for some reason. I use benzos like a tool to beat paralyzing anxiety (as prescribed - PRN). Once I break through an episode, however, I don't generally have to give the anxiety back; it just helps me break through to the other side of anxiety. I know nothing, however, about the relationship between street drugs & anxiety...I just had experience with alcohol - the legal drug.
