Criminal justice client rehabs can be considered as being a significantly better option than jail time or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. For instance, a person who has been found guilty of driving while impaired of alcohol or drugs may qualify for treatment services because of their problem as an alternative to serving time in jail. The judge may even order the individual receive rehab, either alone or as well as other consequences. Very first time offenders specifically tend to be given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it when it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better potential for remaining out of the system after rehabilitation.
