... i've been told before that it take 3-4days for opiates to work their way thru your system and i dont know how accurate that info is... or was. But my point is that my boyfriend is making a valient effort to get off of perks and oxycontin's and has been taking very small intermittent doses of suboxone to deal with the worse of his withdrawl symptoms. and by "small doses" i mean less than a half of a suboxone 8mg a day... unfortunately he has a drug test to take, urine test to b exact and im scared for him to loose his job. can any1 plz offer me some insight to how long it will take for the suboxone to b out of his system so it will not show up in a urine test? Can ne1 plz help me?
