I had my qantas medical last week and returned a positive drug test for opiates (whatever that is)... ended up being cough medicine I took a few days earlier (i got a letter from the pharmisist to confirm he gave me the medicine). I am getting re tested on monday however I am really really worried that this might have dashed my chances of being successful. Anyone ever had a similar experience? will they just chuck my application out the window now??....
