Criminal justice client rehabs can be considered being a significantly better option than time in jail or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. For instance, anyone who has been in prison for driving under the influence of drugs or alcohol may be eligible to obtain treatment services for their problem as opposed to serving time in jail. The judge might even order the individual receive treatment, either alone or in addition to other consequences. Very first time offenders in particular will often be given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it if it is an option. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in rehab have a better chance of remaining out of the judicial system following treatment.
