Criminal justice client rehabs are available as being a considerably better option than prison time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. By way of example, someone who has been in prison for driving drunk of drugs or alcohol may qualify to receive rehabilitation services for his or her problem instead of serving time in jail. The judge could even order the individual receive treatment, either alone or along with other sentencing. First-time offenders in particular tend to be given the chance to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they reap the benefits of it if it is a possibility. The idea behind criminal justice client rehabs is it is way more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been done to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients that take part in rehab have better potential for remaining out of the system following rehab.
