Criminal justice client rehabs are available like a considerably better option than jail time or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For example, somebody who has been in prison for driving drunk of drugs or alcohol may qualify to obtain treatment services for their problem instead of serving time in jail. The judge may even order that the individual receive rehab, either alone or in addition to other sentencing. First-time offenders in particular tend to be given the chance to select a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it if it is a choice. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into treatment than punishment. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that take part in rehabilitation have a better potential for remaining out of the judicial system after treatment.
