Criminal justice client rehabs are available like 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 instance, anyone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to receive rehabilitation services because of their problem as opposed to serving time in jail. The judge may even order the individual receive rehab, either alone or along with other consequences. First-time offenders in particular in many cases are given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it when it is a choice. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into treatment than punishment. Much research has been carried out 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 rehab. The signs and indicators appear to be quite positive, and criminal justice clients that take part in rehab have a better possibility of remaining out of the system after rehabilitation.
