Criminal justice client rehabs are available being a far better option than jail time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. For instance, someone 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 could even order the individual receive rehab, either alone or as well as other consequences. First time offenders specifically will often be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they reap the benefits of it if it is an alternative. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into rehab than punishment. Much research has been completed to discover how effective this process 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 quite positive, and criminal justice clients who do experience rehabilitation have a better potential for remaining out of the judicial system after treatment.
