Criminal justice client rehabs can be considered being a far better option than time in jail or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. By way of example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive treatment services for their problem instead of serving time in jail. The judge could even order that the individual receive rehab, either alone or along with other consequences. First-time offenders in particular tend to be given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it when it is a possibility. The idea behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into treatment than punishment. Much research has been completed to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that do take part in treatment have a better chance of remaining out of the system after treatment.
