How long does soboxen stay in your system to block opiots? If I were to take a soboxen at 2pm then ran out?? How long would it help me restrain from relapsing and just for my own piece of mind... How long will it block opiots from your system? Like hours wise?? If I were to run out and started to withdrawl and got tempted to use, how many hours will the suboxen block opiots after taking it?
