Criminal justice client rehabs are available as a far better option than prison time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. As an example, anyone who has been in prison for dui of drugs or alcohol may qualify to get rehabilitation services for his or her problem as an alternative to serving time in jail. The judge could even order the individual receive treatment, either alone or in addition to other consequences. First-time offenders specifically in many cases are given the ability to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it when it is an option. The idea behind criminal justice client rehabs is that it is way more efficient and effective to invest time and energy into treatment than punishment. Much research has been done to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients that experience treatment have a better possibility of remaining out of the system after rehabilitation.
