Criminal justice client rehabs can be considered being a far better option than time in jail or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. For instance, anyone who has been in prison for driving drunk of drugs or alcohol may qualify to receive treatment services for their problem as opposed to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders in particular will often be given the opportunity to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest commitment into treatment than punishment. Much research has been carried out 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 rehab. All indicators appear to be quite positive, and criminal justice clients who do take part in rehab have a better chance of remaining out of the system following treatment.
