Criminal justice client rehabs can be considered as a significantly better option than prison time or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. By way of example, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible for treatment services for problem as an alternative to serving time in jail. The judge might order the individual receive treatment, either alone or together with other consequences. First-time offenders in particular will often be given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it if it's a choice. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been done to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have better chance of remaining out of the system after rehabilitation.
