Criminal justice client rehabs can be considered being a significantly better option than prison time or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For instance, anyone who has been in prison for driving drunk of alcohol or drugs may qualify to receive treatment services because of their problem rather than serving time in jail. The judge may even order that the individual receive treatment, either alone or as well as other sentencing. First-time offenders specifically tend to be given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it if it's an alternative. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients who do experience rehabilitation have a much better possibility of remaining out of the judicial system following rehabilitation.
