Criminal justice client rehabs can be considered being a considerably better option than time in jail or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible for rehabilitation services for his or her problem as opposed to serving time in jail. The judge may even order that the individual receive treatment, either alone or as well as other consequences. Very first time offenders in particular will often be given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they benefit from it if it is a choice. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been done to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients who take part in rehab have a better probability of remaining out of the judicial system following treatment.
