Criminal justice client rehabs are available as being a far better option than incarceration or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. For instance, someone who has been in prison for driving under the influence of drugs or alcohol may be eligible to get rehabilitation services for his or her problem as an alternative to serving time in jail. The judge might even order the individual receive rehab, either alone or together with other sentencing. First time offenders specifically are often given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it's a choice. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been completed to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients who take part in rehabilitation have a much better potential for remaining out of the system following treatment.
