Criminal justice client rehabs can be considered as being a considerably better option than prison time or significant fines for individuals who have been convicted of any sort of alcohol or drug related crime. For instance, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive rehabilitation services because of their problem rather than serving time in prison. The judge could even order that the individual receive treatment, either alone or along with other sentencing. First time offenders specifically will often be given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they reap the benefits of it if it is a choice. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into rehab than punishment. Much research has been done 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. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in treatment have a better probability of remaining out of the system following rehabilitation.
