Criminal justice client rehabs can be considered as being a considerably better option than prison time or significant fines for individuals who have already been convicted of any type of alcohol or drug related crime. For instance, a person who has been in prison for dui of drugs or alcohol may be eligible to obtain rehab services for his or her problem as opposed to serving time in jail. The judge could even order the individual receive rehabilitation, either alone or in addition to other sentencing. Very first time offenders specifically will often be given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it if it is a possibility. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort 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 treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehabilitation have a better chance of remaining out of the system after treatment.
