Criminal justice client rehabs are available as being a significantly better option than time in jail or heavy fines for individuals who have been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been found guilty of driving under the influence of alcohol or drugs may qualify to receive treatment services for their problem instead of serving time in jail. The judge may even order the individual receive rehab, either alone or together with other consequences. First time offenders specifically tend to be given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it when it is a possibility. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehab than enforcement of other consequences. 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 rehabilitation. All indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have a better possibility of remaining out of the system following treatment.
