Criminal justice client rehabs can be considered like a far better option than prison time or significant fines for individuals who have been convicted of any kind of drug or alcohol related crime. For example, someone who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehab services for his or her problem as an alternative to serving time in jail. The judge may even order that the individual receive treatment, either alone or along with other sentencing. First time offenders specifically will often be given the chance to pick a criminal justice client rehab as opposed 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 it is far 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 strategy 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 experience rehab have better chance of remaining out of the system after rehab.
