Treatment clients referred from the court for drug or alcohol treatment are most commonly referred because they are being given a chance to accept rehabilitation rather than face jail time, other charges, fines, etc. While this is most common among first time offenders, it can be offered at any point including while the person is already incarcerated. There are different types of rehab programs that criminal justice clients may be referred to, and it usually depends on what is available in Wales and the type of drug or alcohol they'll need treatment for.
There are treatment programs that work directly with the courts to treat this specific type of clientele, and are usually publicly-funded or are available at no cost or very little cost to the client. There are also private drug and alcohol recovery programs that might be accepted by the court if there is a specific type of treatment that the person requires or desires that a state-funded facility can't fulfill. The defendant's legal representation can present such options to the judge for acceptance. There are even drug and alcohol rehabilitation programs that provide services from the jails and prisons themselves, whereas clients are typically in a better position for early release or other leniencies when enrolling in drug treatment services while serving their time for a drug related offense or a DUI/DWI.
