Criminal justice client rehabs can be considered as being a considerably better option than time in jail or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For instance, anyone who has been in prison for dui of drugs or alcohol may be eligible for treatment services for their problem rather than serving time in jail. The judge might even order that the individual receive rehab, either alone or along with other consequences. First time offenders specifically will often be given the opportunity to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it when it is an option. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into rehab than punishment. Much research has been completed to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a better potential for remaining out of the system after rehabilitation.
