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 kind of alcohol or drug related crime. For example, anyone who has been found guilty of driving under the influence of drugs or alcohol may qualify to get rehab services for their problem as opposed to serving time in jail. The judge might order the individual receive treatment, either alone or as well as other sentencing. Very first time offenders in particular are often given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been completed to observe how effective this strategy 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 that experience rehab have a better chance of remaining out of the system after treatment.
