Criminal justice client rehabs are available being a considerably better option than incarceration or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. For instance, a person who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehabilitation services for problem instead of serving time in prison. The judge might even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically will often be given the opportunity choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehabilitation than punishment. Much research has been done to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who experience rehab have a much better possibility of remaining out of the judicial system after treatment.
