But the doctor will not continue to treat me with Subutex if I test positive for benzos--Klonipin, which I take for anxiety disorder. The DEA says that the combo is not allowed b/c of the possiblity of overdose--which is extremely remote. How can I give a urine sample that shows the Subutex but not the Klonipin? Are Subutex/Suboxone clinics testing for Subutex levels in addition to other drugs?
