Criminal justice client rehabs can be considered as a significantly better option than incarceration 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 in prison for driving under the influence of alcohol or drugs may qualify for treatment services for their problem as opposed to serving time in jail. The judge may even order that the individual receive treatment, either alone or along with other consequences. First-time offenders specifically tend to be given the opportunity pick a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it is an option. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into treatment than punishment. Much research has been carried out to see how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that take part in treatment have a better possibility of remaining out of the system following rehabilitation.
