Criminal justice client rehabs can be considered being a considerably better option than incarceration or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For instance, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehabilitation services for their problem rather than serving time in prison. The judge might even order the individual receive rehabilitation, either alone or as well as other consequences. First-time offenders in particular are often given the ability to select a criminal justice client rehab instead of 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 it is much more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been done to discover how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that do take part in rehab have better possibility of remaining out of the system following rehab.
