Criminal justice client rehabs can be considered being a far better option than jail time or heavy fines for many who have been convicted of any kind of alcohol or drug related crime. For example, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible to obtain rehabilitation services for problem instead of serving time in jail. The judge could even order the individual receive rehab, either alone or together with other consequences. First time offenders specifically will often be given the chance to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised they reap the benefits of it if it is a possibility. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been carried out to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do experience treatment have better chance of remaining out of the judicial system after rehabilitation.
