Criminal justice client rehabs can be considered being a considerably better option than prison time or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For instance, someone who has been in prison for driving drunk of alcohol or drugs may be eligible for treatment services for his or her problem instead of serving time in jail. The judge could even order the individual receive rehabilitation, either alone or along with other sentencing. Very first time offenders specifically will often be given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it if it is a choice. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehab have a better potential for remaining out of the judicial system following rehab.
