Criminal justice client rehabs can be considered like a considerably better option than incarceration or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. For example, anyone who has been in prison for driving drunk of alcohol or drugs may be eligible to receive rehab services because of their problem rather than serving time in jail. The judge might order the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders in particular will often be given the opportunity choose 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 concept behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who do take part in treatment have a much better probability of remaining out of the judicial system after rehabilitation.
