Criminal justice client rehabs can be considered being a far better option than prison time or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. For instance, anyone who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive rehab services for problem instead of serving time in jail. The judge might order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically are often given the opportunity go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it is a possibility. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients that do experience rehab have a better probability of remaining out of the judicial system following rehabilitation.
