Criminal justice client rehabs are available as being a significantly better option than time in jail or significant fines for individuals who have been convicted of any type of drug or alcohol related crime. For instance, someone who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive treatment services for his or her problem as opposed to serving time in jail. The judge might order that the individual receive rehab, either alone or in addition to other sentencing. First-time offenders in particular will often be given the ability to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they benefit from it when it is a possibility. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into rehab than punishment. Much research has been carried out to see how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have a better chance of remaining out of the system following rehabilitation.
