Criminal justice client rehabs can be considered like a far better option than jail time or significant fines for many who have already been convicted of any sort 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 prison. The judge might even order that the individual receive rehabilitation, either alone or in addition to other sentencing. New offenders in particular in many cases are given the opportunity choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into rehabilitation than punishment. 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 rehab. All indicators seem quite positive, and criminal justice clients who do experience rehab have better probability of remaining out of the judicial system following rehabilitation.
