Criminal justice client rehabs are available being a far better option than time in jail or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For example, anyone who has been in prison for driving drunk of alcohol or drugs may be eligible for treatment services for their problem as an alternative to serving time in jail. The judge might even order that the individual receive treatment, either alone or as well as other consequences. First-time offenders specifically are often given the chance to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they reap the benefits of it when it is an option. The idea behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into rehab than punishment. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the criminal justice client 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 better potential for remaining out of the system after rehabilitation.
