Criminal justice client rehabs can be considered being a far better option than jail time or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. For example, somebody who has been found guilty of driving while impaired of alcohol or drugs may be eligible to obtain rehabilitation services because of their problem as opposed to serving time in prison. The judge may even order the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders in particular tend to be given the chance to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they reap the benefits of it when it is a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been carried out to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that take part in treatment have better probability of remaining out of the system following treatment.
