Criminal justice client rehabs can be considered as being a considerably better option than time in jail or significant fines for many who have been convicted of any kind of alcohol or drug related crime. For example, anyone who has been found guilty of driving drunk of alcohol or drugs may be eligible to obtain rehabilitation services for his or her problem as opposed to serving time in jail. The judge may even order the individual receive rehab, either alone or in addition to other consequences. First-time offenders specifically are often given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it when it is an option. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehab than punishment. Much research has been done to observe how effective this approach 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 experience treatment have a much better potential for remaining out of the judicial system after treatment.
