Criminal justice client rehabs can be considered as a significantly better option than jail time or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. By way of example, a person who has been found guilty of dui of drugs or alcohol may qualify to obtain treatment services for his or her problem instead of serving time in prison. The judge may even order the individual receive treatment, either alone or as well as other sentencing. Very first time offenders specifically in many cases are given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into rehab than punishment. Much research has been done to observe how effective this method 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 who experience rehabilitation have a much better possibility of remaining out of the system following rehabilitation.
