Criminal justice client rehabs are available as being a considerably better option than time in jail or heavy fines for many who have already been convicted of any sort of alcohol or drug related crime. As an example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive rehabilitation services for their problem rather than serving time in jail. The judge might even order the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders in particular tend to be given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it when it is an option. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients that do experience rehab have better potential for remaining out of the judicial system following treatment.
