Criminal justice client rehabs can be considered being a significantly better option than time in jail or significant fines for those who have been convicted of any kind of drug or alcohol related crime. For example, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible for rehab services because of their problem instead of serving time in jail. The judge might order the individual receive rehabilitation, either alone or in addition to other sentencing. Very first time offenders in particular tend to be given the ability to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it if it is an alternative. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into rehab than punishment. Much research has been carried out to observe 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 take part in treatment have a better possibility of remaining out of the judicial system after rehabilitation.
