Criminal justice client rehabs are available as a considerably better option than prison time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive rehabilitation services for his or her problem as opposed to serving time in jail. The judge could even order that the individual receive treatment, either alone or along with other sentencing. New offenders in particular tend to be given the ability to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it when it is an option. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been completed to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that take part in treatment have a much better potential for remaining out of the system following rehabilitation.
