> and substantially reduce their drug use
Drug use is a symptom, the result of another problem. Consider, for example, an undiagnosed personality disorder, or an untreated childhood trauma. Furthermore, what I'm going to mention next isn't helping that either.
> the opportunity for a fresh start
That's just marketing shenanigans. In reality this is rather relative; if one has become a convicted felon, they remain a convicted felon for life. This haunts them till the end of their time. The stigma hampers functionality in society in multiple ways: friendships, and employment first and foremost, but also hypocritically the 2nd amendment (of which I as a European am no proponent of, but what's sauce for the goose is sauce for the gander), and the loss of other rights [1]. This society inhibited perfectionism inhibits a defeatist attitude which lures a convicted felon back on the dark path of criminal behaviour on top of things like personality traits or already financial issues. Prisoner series like Orange Is The New Black (though certainly not the first!) beautifully articulate this specific problem, and a myriad other.
The problem is that we see criminals as individuals who cause an issue in society. Instead, we should regard them as individuals who are unable to participate in society and look at it from that angle, by trying to make them participate in society. Getting rid of the defeatist attitude is one way to increase participation in society, looking for medical treatment. Some examples of problem solving procedures (vary on individual basis) are dental procedure (for e.g. former meth addicts), basic insurance, medicine/drugs (methadone for e.g. former heroin addicts), psychological therapy.
I don't want to be negative about the program, though:
> Fair: The clear demarcation of the offenders’ new supervision conditions and the opportunity for a fresh start allow the offender to regain their sense of self-control. The contract enhances the perceived fairness of any subsequent punishment; this perception of fairness is further supplemented by the sparing rather than harsh level of punishment upon violation, which additionally limits disruption of employment and other non-criminal routines and relationships.
This puts the other parts into perspective, making it indeed more fair for the convicted felon (or less unfair, depending on your perspective). That doesn't mean the sentence itself isn't still out of proportion; it already is put out of proportion because there's societal punishments on top of the sentence. Some of which are harmful for rehabilitation.
Incidentally, fixing this might also make things like arrests generally less violent.
