Criminal justice client rehabs can be considered being a significantly better option than jail time or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For instance, a person who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive treatment services for their problem as an alternative to serving time in jail. The judge might even order that the individual receive treatment, either alone or along with other sentencing. First time offenders specifically tend to be given the ability to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they make the most of it if it is an option. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into rehab than punishment. Much research has been carried out to see how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that do experience treatment have a much better chance of remaining out of the judicial system after treatment.
