Will I get kicked out of my suboxone clinic if I have a dirty urine? I have been going for 9 months and this is the only time I have relapsed. Should I see if I can cancel the appt till next week or just go and tell my doctor everything?

In my area you cannot cancel an appointment for this reason - you used and that use will be detected.

I'd tell the Doctor before he/she finds out some other way and you get kicked out.
