Criminal justice client rehabs can be considered as a far better option than jail time or heavy fines for those who have been convicted of any type of drug or alcohol related crime. For example, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehab services because of their problem instead of serving time in jail. The judge might order the individual receive rehab, either alone or along with other sentencing. First-time offenders in particular are often given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it if it is a possibility. The concept 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 done 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 rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in treatment have a better potential for remaining out of the system after rehab.
