I used to be on the buprenorphine program which is similar to suboxone and I had a urine for pre-employment and asked my doctor how long til it was out of my system. He told me buprenorphine doesnt show up as an opiate or anything else UNLESS they test for it by itself and that costs a lot of money and they'd have to have a suspicion youre on it in the first place! Id try researching to see if bupes have the same ingredients in them as suboxone though first. Good luck!
