Criminal justice client rehabs can be considered as a considerably better option than prison time or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. As an example, anyone who has been in prison for driving drunk of drugs or alcohol may be eligible to receive treatment services for his or her problem rather than serving time in prison. The judge could even order the individual receive treatment, either alone or in addition to other sentencing. New offenders specifically tend to be given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it when it is an option. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into treatment than punishment. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehab have a better possibility of remaining out of the system after treatment.
