Criminal justice client rehabs can be considered as a considerably better option than prison time or heavy fines for many who have already been convicted of any kind of drug or alcohol related crime. For example, a person who has been in prison for driving drunk of drugs or alcohol may be eligible for treatment services for problem as opposed to serving time in jail. The judge may even order the individual receive rehab, either alone or together with other sentencing. First-time offenders in particular are often given the chance to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it when it is a choice. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to see 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 seem quite positive, and criminal justice clients that take part in rehab have a much better possibility of remaining out of the system following rehab.
