Criminal justice client rehabs can be considered like a considerably better option than jail time or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. As an example, somebody who has been in prison for dui of drugs or alcohol may qualify to get rehab services because of their problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or together with other consequences. First time offenders specifically in many cases are given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest commitment into rehab than punishment. Much research has been completed to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients that take part in treatment have a much better potential for remaining out of the judicial system after treatment.
