Criminal justice client rehabs can be considered being a considerably better option than time in jail or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. As an example, a person who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehabilitation services because of their problem as an alternative to serving time in jail. The judge could even order the individual receive rehabilitation, either alone or as well as other consequences. New offenders in particular tend to be given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it if it's a choice. The theory behind criminal justice client rehabs is that 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 see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do experience rehabilitation have a much better probability of remaining out of the system after treatment.
