Criminal justice client rehabs are available as being a far better option than jail time or heavy fines for those who have been convicted of any type of drug or alcohol related crime. For example, anyone who has been in prison for driving drunk of drugs or alcohol may be eligible to receive rehabilitation services because of their problem rather than serving time in jail. The judge could even order the individual receive rehab, either alone or in addition to other consequences. Very first time offenders specifically are often given the chance to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it when it is an option. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients that do experience rehab have a much better possibility of remaining out of the judicial system following rehabilitation.
