Criminal justice client rehabs can be considered as a considerably better option than time in jail or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, a person who has been in prison for driving while impaired of drugs or alcohol may be eligible to obtain rehabilitation services for their problem instead of serving time in prison. The judge may even order that the individual receive treatment, either alone or together with other consequences. Very first time offenders specifically are often given the chance to select a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into treatment than punishment. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients that do experience rehab have better chance of remaining out of the system following treatment.
