At my clinic, fail or come up 'non-therapeutic' as they put it, and you will have your step-level decreased. This means if you are on monthly take-homes, then you go back to bi-monthly. If you are on the weekly phase, as I am, then you will be reverted back to 3x week.
If you are daily, and fail a UA, nothing really happens except it'll take longer to progress. You have to have 3 'therapeutic' UA's, and some classes completed to increase or phase up your step-level.
If you aren't accruing any clean UA's, then you're gonna be daily for the foresee-able future. For some people this is no big deal.....I know some who have been daily for years....they piss dirty, and just keep showing up they keep getting dosed.
Benzos are the only thing that if you piss dirty for them, you'll get kicked the fuck out. And it still takes a while of them saying 'hey, don't do that' before you are up for termination.
I think for the most part clinics are pretty tolerable of people cross-using, as long as it's not benzos.
That's MY experience....Florida could be entirely different.
