Criminal justice client rehabs can be considered being a significantly better option than incarceration or significant fines for individuals who have been convicted of any type of alcohol or drug related crime. For instance, someone who has been in prison for dui of alcohol or drugs may qualify to receive rehab services for their problem rather than serving time in prison. The judge might even order the individual receive rehab, either alone or along with other sentencing. First-time offenders specifically tend to be given the chance to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it when it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into rehab than punishment. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that do experience rehabilitation have a better chance of remaining out of the judicial system following rehab.
