Criminal justice client rehabs can be considered like a significantly better option than prison time or significant fines for those who have been convicted of any kind of drug or alcohol related crime. For instance, somebody who has been found guilty of driving under the influence of drugs or alcohol may qualify to receive rehabilitation services for their problem as an alternative to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or as well as other consequences. First-time offenders specifically will often be given the ability to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they benefit from it when it is a choice. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest commitment into rehab than punishment. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that do take part in rehab have a much better probability of remaining out of the system after rehab.
