Criminal justice client rehabs are available as being a significantly better option than prison time or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. By way of example, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible for rehab services for problem rather than serving time in jail. The judge could even order that the individual receive treatment, either alone or together with other sentencing. Very first time offenders in particular tend to be given the ability to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it if it is a choice. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients that take part in treatment have better chance of remaining out of the judicial system after rehab.
