Criminal justice client rehabs can be considered being a far better option than time in jail or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. For instance, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify for rehab services because of their problem instead of serving time in prison. The judge might order the individual receive rehab, either alone or in addition to other consequences. First-time offenders in particular are often given the ability to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most 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 effort into rehabilitation than enforcement of other consequences. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that take part in treatment have a better chance of remaining out of the system following rehabilitation.
