Criminal justice client rehabs can be considered as being a far better option than jail time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. For example, anyone who has been in prison for dui of alcohol or drugs may be eligible to receive rehab services for their problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or along with other consequences. New offenders in particular in many cases are given the opportunity pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they make the most of it when it is a possibility. The idea 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 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 rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have better possibility of remaining out of the judicial system following treatment.
