Criminal justice client rehabs can be considered being a significantly better option than time in jail or heavy fines for many who have already been convicted of any sort of alcohol or drug related crime. As an example, a person who has been found guilty of driving drunk of drugs or alcohol may qualify to obtain rehabilitation services for problem instead of serving time in prison. The judge may even order the individual receive treatment, either alone or together with other sentencing. First-time offenders in particular will often be given the opportunity pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that do experience rehab have better chance of remaining out of the system after rehab.
