Criminal justice client rehabs can be considered being a far better option than time in jail or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, anyone who has been in prison for driving drunk of alcohol or drugs may be eligible to obtain rehab services for problem rather than serving time in prison. The judge might even order the individual receive treatment, either alone or as well as other sentencing. Very first time offenders specifically are often given the chance to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it is an option. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into treatment than punishment. Much research has been carried out to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. 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.
