Criminal justice client rehabs can be considered being a significantly better option than jail time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. As an example, anyone who has been found guilty of driving while impaired of drugs or alcohol may be eligible to receive treatment services because of their problem instead of serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or together with other consequences. First-time offenders specifically will often be given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they make the most of it if it is a possibility. The concept behind criminal justice client rehabs is it is way more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been completed to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehab have a much better potential for remaining out of the judicial system after rehab.
