Criminal justice client rehabs are available like a far better option than time in jail or heavy fines for many who have already been convicted of any type of alcohol or drug related crime. For instance, someone who has been in prison for dui of drugs or alcohol may be eligible to receive treatment services for their problem rather than serving time in jail. The judge could even order that the individual receive rehab, either alone or along with other consequences. First-time offenders in particular in many cases are given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it when it is an alternative. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been completed to see how effective this strategy 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 possibility of remaining out of the system following rehab.
