Criminal justice client rehabs can be considered as a far better option than jail time or heavy fines for individuals who have been convicted of any kind of alcohol or drug related crime. For example, someone who has been in prison for driving drunk of drugs or alcohol may be eligible to receive treatment services because of their problem instead of serving time in jail. The judge might order the individual receive rehabilitation, either alone or along with other sentencing. First time offenders specifically in many cases are given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest commitment into treatment than punishment. Much research has been done to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that do experience treatment have a much better chance of remaining out of the system following rehab.
