Criminal justice client rehabs can be considered as a significantly better option than incarceration or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. For instance, somebody who has been in prison for driving while impaired of drugs or alcohol may qualify to receive rehabilitation services for his or her problem instead of serving time in jail. The judge may even order the individual receive treatment, either alone or in addition to other consequences. First-time offenders specifically will often be given the opportunity to choose 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 that it is way more effective and efficient to invest time and energy into rehab 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 individual 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 rehabilitation have a better chance of remaining out of the system following rehab.
