Criminal justice client rehabs are available as a far better option than incarceration or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. For instance, somebody who has been in prison for driving under the influence of drugs or alcohol may qualify to get treatment services because of their problem as an alternative to serving time in jail. The judge might even order the individual receive rehabilitation, either alone or together with other consequences. Very first time offenders in particular in many cases are given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they benefit from 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 effort into rehab than punishment. Much research has been completed to see 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 appear to be quite positive, and criminal justice clients who do experience treatment have a better probability of remaining out of the system following rehab.
