Criminal justice client rehabs can be considered as a considerably better option than prison time or significant fines for those who have already been convicted of any type of alcohol or drug related crime. For instance, somebody who has been in prison for driving under the influence of drugs or alcohol may be eligible to get treatment services for his or her problem as opposed to serving time in prison. The judge might even order that the individual receive treatment, either alone or together with other consequences. First time offenders in particular in many cases are given the opportunity to pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it when it is a choice. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who take part in treatment have a much better chance of remaining out of the system after rehab.
