Criminal justice client rehabs are available as being a considerably better option than prison time or heavy fines for individuals who have been convicted of any kind of drug or alcohol related crime. As an example, a person who has been in prison for driving drunk of alcohol or drugs may qualify for treatment services for his or her problem rather than serving time in prison. The judge might even order the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders in particular will often be given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it when it is an option. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehab than punishment. Much research has been completed to see how effective this approach 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 rehab have better chance of remaining out of the system following treatment.
