Criminal justice client rehabs are available like a significantly better option than time in jail or heavy fines for those who have been convicted of any type of drug or alcohol related crime. By way of example, someone who has been in prison for driving while impaired of alcohol or drugs may be eligible for rehabilitation services because of their problem as opposed to serving time in prison. The judge could even order the individual receive treatment, either alone or along with other sentencing. First-time offenders in particular are often given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients who do experience rehab have better possibility of remaining out of the system after rehab.
