Criminal justice client rehabs are available like a considerably better option than incarceration or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For example, somebody who has been found guilty of driving drunk of drugs or alcohol may be eligible to receive rehab services for their problem as an alternative to serving time in jail. The judge might even order the individual receive rehab, either alone or along with other sentencing. New offenders specifically in many cases are given the opportunity go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it if it is an alternative. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehab than punishment. Much research has been completed to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who take part in treatment have a better possibility of remaining out of the system after rehabilitation.
