It will depend totally on what test they use. If they use a simple five panel test it won't show up as anything ... it will be as if you were taking nothing. But some of the much larger panels also include a test specifically for buprenorphine (the drug in suboxone). Why risk it if you're doing it recreationally and placing your job at risk? Not judging you that just doesn't make sense to me. Good luck and God bless.
