Clients referred from the court for drug or alcohol treatment are usually referred because they are being granted a chance to try their hand at rehabilitation instead of jail time, other charges, fines, etc. Although this is more prevalent among first time offenders, it can occur at any time including while the defendant is already incarcerated. There are different types of facilities that offenders can be referred to, and this all depends on which programs are attainable in Polk and the type of substance they'll need treatment for.
There are programs that work directly with the courts to treat this specific type of clientele, and are typically state or federally funded or are available at no cost or very little cost to the client. There are also private substance abuse recovery facilities that might be authorized by the court if there is a specific type of recovery method that the client needs or wants that a state-funded program can't fulfill. The client's legal representation can push for such options to the judge for permission. There are even drug treatment centers that provide services from the jails and prisons themselves, whereas clients are typically in a better position for early release or other benefits when participating in substance abuse treatment services while serving their time for a drug related offense or a DUI/DWI.
