Criminal justice client rehabs can be considered as a considerably better option than jail time or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. As an example, somebody who has been found guilty of driving drunk of drugs or alcohol may be eligible to receive treatment services because of their problem instead of serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or as well as other sentencing. First-time offenders in particular are often given the opportunity choose a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is a choice. The concept 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 done to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in treatment have better chance of remaining out of the system following rehab.
