Criminal justice client rehabs are available as being a significantly better option than prison time or significant fines for individuals who have been convicted of any type of drug or alcohol related crime. For instance, someone who has been in prison for dui of drugs or alcohol may qualify to receive treatment services for their problem as an alternative to serving time in jail. The judge could even order the individual receive rehabilitation, either alone or as well as other consequences. First time offenders in particular will often be given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who take part in rehabilitation have better chance of remaining out of the judicial system following treatment.
