Criminal justice client rehabs can be considered as being a considerably better option than incarceration or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. By way of example, a person who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive rehabilitation services for their problem as an alternative to serving time in jail. The judge might order the individual receive rehabilitation, either alone or as well as other sentencing. First time offenders specifically tend to be given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it if it is an alternative. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into treatment than punishment. Much research has been carried out 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 treatment. All indicators appear to be quite positive, and criminal justice clients who experience rehab have better potential for remaining out of the system after rehab.
