Criminal justice client rehabs are available like a considerably better option than time in jail or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. For example, someone who has been in prison for dui of alcohol or drugs may be eligible to obtain treatment services because of their problem as opposed to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or along with other sentencing. First-time offenders in particular in many cases are given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it if it is a possibility. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that take part in rehabilitation have a better possibility of remaining out of the judicial system after treatment.
