Criminal justice client rehabs are available as being a significantly better option than jail time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. For instance, a person who has been found guilty of driving under the influence of alcohol or drugs may be eligible to obtain treatment services for his or her problem as opposed to serving time in jail. The judge might order the individual receive treatment, either alone or in addition to other sentencing. First time offenders in particular tend to be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it if it is an option. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been completed to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients who do take part in rehab have better chance of remaining out of the system after treatment.
