I have a probation drug test coming up that truly decides my fate. The day of my urine drug test I will be eighteen days clean from suboxone and ten days clean from heroin. Yes they so drug test for subs. I took it for four days. Four milligrams the first two days and two milligrams day three and four. Do you think I have a chance for passing? I have a slow metabolism and not active and overweight. Also... any suggestions on what I could do to flush it out quicker? Im terrified... any input would be appreciated.
