Criminal justice client rehabs can be considered being a far better option than jail time or heavy fines for those who have been convicted of any type of drug or alcohol related crime. As an example, someone who has been found guilty of driving under the influence of drugs or alcohol may be eligible for rehabilitation services for problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders in particular will often be given the opportunity go with a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it if it is an alternative. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been completed to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehab have a much better probability of remaining out of the system following treatment.
