Criminal justice client rehabs can be considered being a considerably better option than jail time or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. As an example, someone who has been in prison for dui of drugs or alcohol may be eligible to receive treatment services for their problem rather than serving time in jail. The judge may even order the individual receive treatment, either alone or as well as other consequences. First time offenders in particular in many cases are given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it if it's a choice. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients that take part in rehab have better possibility of remaining out of the system following rehabilitation.
