Criminal justice client rehabs can be considered like a significantly better option than time in jail or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For instance, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible to get treatment services for his or her problem rather than serving time in prison. The judge could even order the individual receive rehabilitation, either alone or in addition to other sentencing. Very first time offenders in particular will often be given the ability to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it when it is an option. 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 discover 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 who do experience treatment have a much better probability of remaining out of the judicial system following rehab.
