Criminal justice client rehabs can be considered as a considerably better option than time in jail or significant fines for many who have been convicted of any type of drug or alcohol related crime. As an example, a person who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehab services for his or her problem as opposed to serving time in prison. 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 chance to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it if it is a choice. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients that experience rehab have a better chance of remaining out of the judicial system following rehab.
