I think that's just until you've stabilised, at least where I live. They don't trust us much in those early days; they test us every day, and make us come in for meth every day, and yeah, it's a major hassle, but it's still far more convenient than chasing down bags and money every hour of the day imo. Here, when you provide enough clean urine, and turn up for appointments, they start giving you weekly scripts, and monthly tests. Do that for long enough, and you're eligible for "shared car"-no tests, no appointments, no dealing with drug treatment providers: you just get your scripts monthly from your regular doctor. Course, many people on this scheme tend to stay on it for decades, if not life.
