Criminal justice client rehabs can be considered like a considerably better option than time in jail or heavy fines for individuals who have been convicted of any type of alcohol or drug related crime. By way of example, anyone who has been in prison for driving drunk of drugs or alcohol may be eligible for treatment services because of their problem instead of serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or together with other consequences. First-time offenders in particular will often be given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is a choice. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better probability of remaining out of the system after rehab.
