Criminal justice client rehabs are available as being a considerably better option than time in jail or heavy fines for many who have been convicted of any sort of alcohol or drug related crime. For instance, somebody who has been in prison for driving while impaired of drugs or alcohol may be eligible to obtain treatment services for problem instead of serving time in prison. The judge may even order the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders in particular are often given the opportunity pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it if it is a possibility. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehab have a much better chance of remaining out of the system after rehab.
