Criminal justice client rehabs can be considered as being a significantly better option than time in jail or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, someone who has been found guilty of driving drunk of alcohol or drugs may be eligible for rehabilitation services because of their problem as an alternative to serving time in jail. The judge could even order that the individual receive treatment, either alone or as well as other sentencing. First-time offenders in particular will often be given the opportunity go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest commitment into rehabilitation than punishment. Much research has been completed to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better possibility of remaining out of the system after rehabilitation.
