Criminal justice client rehabs can be considered as a considerably better option than prison time or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. As an example, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive rehab services for his or her problem rather than serving time in jail. The judge could even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically will often be given the opportunity select a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it when it is an alternative. The concept behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehab than punishment. Much research has been completed 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 rehabilitation. All indicators seem to be quite positive, and criminal justice clients that do experience treatment have better potential for remaining out of the judicial system after treatment.
