Criminal justice client rehabs are available like a significantly better option than prison time or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. By way of example, a person who has been in prison for driving while impaired of alcohol or drugs may be eligible for rehabilitation services because of their problem as opposed to serving time in prison. The judge might order the individual receive rehabilitation, either alone or together with other consequences. Very first time offenders in particular in many cases are given the chance to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehab than punishment. Much research has been done to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have a much better potential for remaining out of the judicial system after treatment.
