Criminal justice client rehabs can be considered like a significantly better option than jail time or significant fines for individuals who have been convicted of any sort of drug or alcohol related crime. For example, a person 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 even order that the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders specifically in many cases are given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is well-advised they reap the benefits of it when it is an option. 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 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 appear to be quite positive, and criminal justice clients who do experience treatment have a much better possibility of remaining out of the judicial system following treatment.
