Criminal justice client rehabs are available like a considerably better option than prison time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, a person who has been in prison for driving while impaired of alcohol or drugs may be eligible to get rehab services for his or her problem instead of serving time in prison. The judge might even order the individual receive rehab, either alone or together with other sentencing. Very first time offenders specifically will often be given the opportunity select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehab than punishment. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have a much better potential for remaining out of the system following rehab.
