Criminal justice client rehabs are available as being a considerably better option than time in jail or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. By way of example, a person who has been in prison for driving drunk of drugs or alcohol may be eligible to get rehab services for his or her problem rather than serving time in jail. The judge may even order that the individual receive treatment, either alone or together with other sentencing. Very 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 make the most of it when it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into rehab than punishment. Much research has been completed to see how effective this method 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 who experience rehab have better possibility of remaining out of the judicial system following treatment.
