Criminal justice client rehabs are available as a considerably better option than time in jail or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For instance, someone who has been in prison for driving drunk of alcohol or drugs may be eligible to obtain rehab services because of their problem rather than serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders in particular tend to be given the ability to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it if it's an option. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been completed to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who experience rehab have a better possibility of remaining out of the system following treatment.
