Criminal justice client rehabs are available like a considerably better option than time in jail or heavy fines for individuals who have been convicted of any type of alcohol or drug related crime. By way of example, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible for treatment services for his or her problem as opposed to serving time in jail. The judge may even order that the individual receive treatment, either alone or in addition to other consequences. First time offenders in particular will often be given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended that they benefit from it when it is a choice. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehab than enforcement of other consequences. 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 potential for remaining out of the system following rehab.
