Criminal justice client rehabs are available like a considerably better option than prison time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible to obtain rehab services for their problem as an alternative to serving time in prison. The judge might even order the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders specifically will often be given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it when it is a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehab than punishment. 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 rehabilitation. All indicators seem quite positive, and criminal justice clients that take part in treatment have a much better chance of remaining out of the system following rehabilitation.
