Criminal justice client rehabs are available like a considerably better option than time in jail or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. For instance, a person who has been in prison for driving while impaired of drugs or alcohol may be eligible to get rehab services for their problem rather than serving time in prison. The judge might order the individual receive rehab, either alone or along with other sentencing. First time offenders specifically in many cases are given the chance to pick a criminal justice client rehab rather than other sentencing, and it is well-advised they make the most of it if it is a choice. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment 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 treatment. All indicators seem to be quite positive, and criminal justice clients that take part in treatment have a better potential for remaining out of the system following treatment.
