Criminal justice client rehabs are available as being a significantly better option than time in jail or significant fines for those who have already been convicted of any type of alcohol or drug related crime. For example, somebody who has been found guilty of driving drunk of alcohol or drugs may qualify to receive treatment services for their problem as an alternative to serving time in prison. The judge may even order the individual receive rehabilitation, either alone or along with other sentencing. Very first time offenders in particular will often be given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it is an option. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been done to discover 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 appear to be quite positive, and criminal justice clients who do take part in treatment have a better chance of remaining out of the judicial system following rehab.
