Criminal justice client rehabs can be considered as being a considerably better option than prison time or significant fines for many who have been convicted of any kind of drug or alcohol related crime. For example, anyone who has been in prison for driving while impaired of alcohol or drugs may qualify to receive rehab services because of their problem as opposed to serving time in prison. The judge might even order the individual receive treatment, either alone or together with other sentencing. Very first time offenders specifically in many cases are given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into treatment than punishment. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do experience rehab have a better probability of remaining out of the judicial system following rehabilitation.
