Criminal justice client rehabs can be considered as a significantly better option than prison time or significant fines for many who have already been convicted of any type of alcohol or drug related crime. As an example, someone who has been in prison for dui of alcohol or drugs may qualify to receive rehab services because of their problem as an alternative to serving time in jail. The judge might even order the individual receive rehab, either alone or in addition to other sentencing. Very first time offenders specifically tend to be given the chance to go with a criminal justice client rehab instead of other sentencing, and it is well-advised they reap the benefits of it when it is an option. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehab than punishment. Much research has been completed to find out how effective this process 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 that do take part in treatment have a much better potential for remaining out of the judicial system following treatment.
