Criminal justice client rehabs can be considered as being a significantly better option than time in jail or heavy fines for those who have been convicted of any type of drug or alcohol related crime. For example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive treatment services for their problem instead of serving time in prison. The judge might order the individual receive rehabilitation, either alone or as well as other consequences. First time offenders specifically will often be given the opportunity go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it when it is an option. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest time and effort into treatment than punishment. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who experience rehabilitation have better probability of remaining out of the system following rehabilitation.
