Criminal justice client rehabs are available as a considerably better option than time in jail or significant fines for those who have been convicted of any kind of drug or alcohol related crime. As an example, a person who has been in prison for dui of alcohol or drugs may qualify to receive rehabilitation services for their problem as opposed to serving time in jail. The judge may even order the individual receive treatment, either alone or along with other consequences. First time offenders specifically are often given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it is an option. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehab than punishment. Much research has been completed to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehab have a better potential for remaining out of the system following rehabilitation.
