Criminal justice client rehabs can be considered being a far better option than jail time or significant fines for those who have been convicted of any sort of alcohol or drug related crime. For instance, someone who has been in prison for driving under the influence of drugs or alcohol may qualify for rehab services for problem as opposed to serving time in jail. The judge could even order the individual receive rehab, either alone or together with other sentencing. First time offenders specifically are often given the opportunity choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it when it is a choice. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who experience treatment have better chance of remaining out of the system following treatment.
