Criminal justice client rehabs can be considered being a significantly better option than time in jail or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. For instance, anyone who has been found guilty of driving while impaired of alcohol or drugs may be eligible to receive rehabilitation services because of their problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or in addition to other sentencing. New offenders specifically tend to be given the ability to select a criminal justice client rehab rather than other sentencing, and it is well-advised they make the most of it if it is a possibility. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to find out how effective this process 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 take part in rehab have a better chance of remaining out of the system after treatment.
