Criminal justice client rehabs are available like a far better option than time in jail or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. For instance, someone who has been in prison for driving under the influence of drugs or alcohol may qualify to get rehab services because of their problem instead of serving time in prison. The judge might order that the individual receive rehabilitation, either alone or together with other consequences. First-time offenders in particular are often given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is highly recommended that they benefit from it if it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into treatment than punishment. Much research has been completed to find out how effective this method 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 that do take part in rehabilitation have a much better potential for remaining out of the judicial system following rehabilitation.
