Criminal justice client rehabs can be considered as being a considerably better option than time in jail or heavy fines for individuals who have already been convicted of any type of alcohol or drug related crime. For instance, a person who has been found guilty of dui of alcohol or drugs may qualify to obtain rehabilitation services for their problem as opposed to serving time in jail. The judge might even order the individual receive treatment, either alone or along with other sentencing. First-time offenders specifically will often be given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it when it is an option. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehab than punishment. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients that take part in rehab have a much better possibility of remaining out of the system following treatment.
