Criminal justice client rehabs can be considered being a considerably better option than jail time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. By way of example, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible to receive rehabilitation services for their problem as opposed to serving time in jail. The judge may even order the individual receive treatment, either alone or together with other consequences. Very first time offenders specifically in many cases are given the ability to select a criminal justice client rehab instead of other sentencing, and it is highly recommended they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest time and effort into rehab than punishment. Much research has been done to see how effective this approach 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 take part in treatment have better chance of remaining out of the judicial system after treatment.
