Criminal justice client rehabs can be considered being a considerably better option than time in jail or significant fines for many who have 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 drugs or alcohol may qualify to obtain rehab services for their problem instead of serving time in jail. The judge might even order that the individual receive rehab, either alone or together with other sentencing. First time offenders in particular are often given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they reap the benefits of it if it's a possibility. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been completed to observe 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 seem to be quite positive, and criminal justice clients who do take part in rehabilitation have a better possibility of remaining out of the system after rehabilitation.
