Criminal justice client rehabs are available as a far better option than incarceration or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. By way of example, someone who has been found guilty of driving drunk of drugs or alcohol may be eligible to get rehabilitation services because of their problem as opposed to serving time in jail. The judge might order the individual receive rehab, either alone or along with other sentencing. First-time offenders specifically in many cases are given the opportunity go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits of it when it is a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and energy into rehab 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 criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that do experience rehab have a better potential for remaining out of the system after rehabilitation.
