Criminal justice client rehabs can be considered as a far better option than jail time or heavy fines for many who have been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for driving while impaired of drugs or alcohol may qualify to receive treatment services because of their problem rather than serving time in prison. The judge could even order that the individual receive rehab, either alone or in addition to other consequences. Very first time offenders in particular will often be given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they benefit from it if it is a possibility. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that experience rehab have a much better potential for remaining out of the judicial system after rehabilitation.
