Criminal justice client rehabs can be considered like a far better option than jail time or significant fines for those who have been convicted of any type of drug or alcohol related crime. For example, anyone who has been in prison for driving while impaired of drugs or alcohol may qualify to obtain rehabilitation services because of their problem as an alternative to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or as well as other consequences. First time offenders specifically will often be given the chance to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest commitment into rehab than punishment. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who experience rehabilitation have better probability of remaining out of the system after rehabilitation.
