Criminal justice client rehabs can be considered as being a significantly better option than prison time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. By way of example, anyone who has been found guilty of driving under the influence of alcohol or drugs may qualify for rehab services because of their problem rather than serving time in prison. The judge might even order the individual receive rehabilitation, either alone or in addition to other sentencing. Very first time offenders specifically will often be given the chance to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into rehab than enforcement of other consequences. Much research has been completed to observe how effective this strategy 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 rehabilitation have a much better probability of remaining out of the system after treatment.
