Criminal justice client rehabs are available like a significantly better option than time in jail or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. As an example, somebody who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive treatment services for problem instead of serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders specifically will often be given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it if it is an option. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been done 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 treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have a better possibility of remaining out of the system following rehab.
