Criminal justice client rehabs are available as being a far better option than prison time or heavy fines for many who have been convicted of any kind of drug or alcohol related crime. For instance, anyone who has been in prison for dui of alcohol or drugs may be eligible to obtain rehab services for their problem as opposed to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or in addition to other sentencing. Very first time offenders in particular in many cases are given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out 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 treatment. All indicators seem quite positive, and criminal justice clients who do take part in treatment have a better chance of remaining out of the judicial system following treatment.
