Criminal justice client rehabs are available as being a considerably better option than jail time or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. For instance, somebody who has been in prison for driving drunk of alcohol or drugs may be eligible to receive rehabilitation services for his or her problem instead of serving time in jail. The judge might even order the individual receive rehab, either alone or together with other consequences. Very first time offenders in particular will often be given the ability to select a criminal justice client rehab instead of other sentencing, and it is highly recommended that they take advantage of it when it is a possibility. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into treatment than punishment. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that do take part in treatment have a much better chance of remaining out of the judicial system after rehab.
