Criminal justice client rehabs are available as a considerably better option than time in jail or significant fines for individuals who have been convicted of any type of drug or alcohol related crime. By way of example, a person who has been in prison for dui of alcohol or drugs may qualify to obtain rehabilitation services for their problem instead of serving time in prison. The judge might order that the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders in particular in many cases are given the ability to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and energy into rehabilitation than punishment. Much research has been completed to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients who do take part in treatment have a much better potential for remaining out of the system after rehab.
