Suboxone is the combo drug with the opioid blocker Subutex is buprenorphine only but I guess you know that and I really shouldn't even mention that.

Don't use any marijuana for 2 months then while taking your suboxone as prescribed store and freeze that urine for a year's worth of tests and sub with it at the doctor's office. Have you ever had a drug test from the doctor before so that you know their procedures.
