Criminal justice client rehabs can be considered as a considerably better option than prison time or significant fines for those who have been convicted of any kind of alcohol or drug related crime. For example, someone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to get rehab services for his or her problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or together with other sentencing. Very first time offenders specifically tend to be given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it is a possibility. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been completed to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that do experience rehab have better potential for remaining out of the system after treatment.
