Criminal justice client rehabs can be considered being a far 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 example, someone who has been in prison for driving while impaired of alcohol or drugs may be eligible to get rehab services for his or her problem as an alternative to serving time in prison. The judge could even order the individual receive rehabilitation, either alone or together with other sentencing. First time offenders specifically will often be given the opportunity pick a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been completed to discover how effective this approach 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 take part in rehab have a much better potential for remaining out of the judicial system following rehab.
