Criminal justice client rehabs can be considered like a considerably better option than incarceration or heavy fines for many who have been convicted of any type of alcohol or drug related crime. For example, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible to get treatment services for his or her problem as opposed to serving time in prison. The judge may even order the individual receive treatment, either alone or along with other sentencing. First time offenders specifically will often be given the chance to go with a criminal justice client rehab instead of other sentencing, and it is well-advised that they make the most of it if it is an alternative. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into treatment than punishment. Much research has been completed to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who do experience rehab have better chance of remaining out of the system after rehab.
