I was drug tested very often on multiple occasions and did dxm frequently during those times.. never got tested positive for anything. You should be fine, I got tested by my probation officer, a few rehab places.. School when I was a kid.. My own mother drug tested me sometimes..
Never dropped for anything. I went into a drug test while on dxm. Theres a funny story behind that one. I COULDNT PEE standing up and especially not with the dude looking at me. They knew I was on something, but the test came negative for everything. You know how dxm makes your bladder do weird things? xD
