Criminal justice client rehabs are available as being a considerably better option than prison time or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. As an example, someone who has been found guilty of driving under the influence of alcohol or drugs may be eligible for rehabilitation services for their problem as an alternative to serving time in prison. The judge may even order the individual receive rehabilitation, either alone or along with other consequences. First time offenders specifically are often given the ability to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they make the most of it if it is an option. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into rehab than punishment. Much research has been completed to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients that take part in rehabilitation have better probability of remaining out of the system following treatment.
