Criminal justice client rehabs are available as being a far better option than prison time or heavy fines for those who have been convicted of any kind of drug or alcohol related crime. For example, a person who has been in prison for dui of drugs or alcohol may be eligible to get rehabilitation services because of their problem rather than serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders specifically tend to be given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it if it is an option. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been done 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. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in treatment have better possibility of remaining out of the judicial system following rehab.
