Criminal justice client rehabs can be considered like a considerably better option than time in jail or significant fines for many who have already been convicted of any kind of alcohol or drug related crime. For instance, a person who has been found guilty of driving under the influence of alcohol or drugs may be eligible for rehab services for their problem rather than serving time in prison. The judge could even order the individual receive treatment, either alone or in addition to other consequences. Very first time offenders in particular tend to be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it when it is a choice. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been done 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 to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better potential for remaining out of the system following treatment.
