Criminal justice client rehabs are available being a significantly better option than prison time or significant fines for many who have already been convicted of any kind of alcohol or drug related crime. As an example, someone who has been in prison for driving drunk of alcohol or drugs may be eligible to obtain rehabilitation services because of their problem as opposed to serving time in jail. The judge might even order that the individual receive treatment, either alone or in addition to other sentencing. Very first time offenders specifically will often be given the chance to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended they make the most of it when it is an option. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into treatment 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 seem quite positive, and criminal justice clients who experience treatment have better possibility of remaining out of the system following rehabilitation.
