How much time does it take for one 8mg strip of Suboxone to not show up in your urine?

Testing. are you being specifically tested for buprenorphine? a standard urine drug panel will not test positive for use of buprenorphine. if they are tesing specifically for the buprenorphine it could take more than 5-6 days to exit your system. if its an employment drug test and they are doing a random screen, chances are that you won't test positive for opiates - assuming no use of other opiates.
