Criminal justice client rehabs can be considered as being a considerably better option than prison time or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For instance, someone who has been in prison for driving while impaired 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 the individual receive rehab, either alone or along with other sentencing. First time offenders specifically in many cases are given the opportunity select 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 a choice. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been done to find out how effective this approach 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 to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better chance of remaining out of the judicial system following treatment.
