Criminal justice client rehabs can be considered as being a significantly better option than time in jail or heavy fines for individuals who have been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for driving drunk of alcohol or drugs may be eligible to receive treatment services because of their problem as an alternative to serving time in prison. The judge might order the individual receive rehabilitation, 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 they reap the benefits of it when it is an option. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into rehab than enforcement of other consequences. Much research has been completed to observe how effective this method 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 who experience rehabilitation have better probability of remaining out of the system after rehabilitation.
