Criminal justice client rehabs can be considered as being a considerably better option than jail time or heavy fines for individuals who have been convicted of any type of drug or alcohol related crime. As an example, a person who has been in prison for driving under the influence of drugs or alcohol may qualify to get treatment services for his or her problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders in particular are often given the chance to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it if it's a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to discover 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 seem to be quite positive, and criminal justice clients that do take part in treatment have better potential for remaining out of the system following treatment.
