Criminal justice client rehabs can be considered being a far better option than jail time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, someone who has been in prison for driving drunk of alcohol or drugs may be eligible to receive treatment services because of their problem as opposed to serving time in jail. The judge might order that the individual receive rehab, either alone or as well as other sentencing. First time offenders specifically will often be given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it if it is a possibility. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into treatment than punishment. Much research has been completed to discover 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 quite positive, and criminal justice clients that experience rehab have a better probability of remaining out of the judicial system following treatment.
