Criminal justice client rehabs are available being a significantly better option than incarceration or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For instance, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify to receive rehabilitation services for his or her problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or together with other consequences. First-time offenders specifically will often be given the chance to select a criminal justice client rehab rather than other sentencing, and it is highly recommended they reap the benefits of it if it is an option. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time 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 treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do experience rehab have a better possibility of remaining out of the judicial system following treatment.
