Criminal justice client rehabs can be considered like a significantly better option than prison time or heavy fines for those who have been convicted of any type of drug or alcohol related crime. For example, anyone who has been found guilty of driving drunk of alcohol or drugs may be eligible to receive rehabilitation services for their problem as opposed to serving time in prison. The judge might even order that the individual receive treatment, either alone or together with other sentencing. First-time offenders in particular in many cases are given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it when it is a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehab than punishment. Much research has been carried out to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who experience rehabilitation have better chance of remaining out of the judicial system following rehab.
