Criminal justice client rehabs are available as a far better option than incarceration or significant fines for many who have already been convicted of any type of alcohol or drug related crime. For example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to receive treatment services for problem as an alternative to serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders in particular in many cases are given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is an option. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been completed to find out 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 possibility of remaining out of the system after rehab.
