Criminal justice client rehabs can be considered as a far better option than prison time or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, somebody who has been in prison for dui of alcohol or drugs may qualify to receive rehab services for problem rather than serving time in prison. The judge could even order that the individual receive treatment, either alone or in addition to other consequences. First-time offenders specifically in many cases are given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it's an option. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that do take part in treatment have better chance of remaining out of the judicial system following rehab.
