Criminal justice client rehabs are available like a far better option than incarceration or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. For example, someone who has been in prison for driving drunk of drugs or alcohol may be eligible to obtain rehab services for his or her problem as an alternative to serving time in jail. The judge could even order the individual receive rehabilitation, either alone or together with other sentencing. New offenders specifically tend to be given the chance to pick a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it when it is a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into treatment than punishment. Much research has been completed to see how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients that do take part in rehab have a much better potential for remaining out of the system following rehabilitation.
