Criminal justice client rehabs are available as being a significantly better option than incarceration or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For instance, anyone who has been found guilty of driving while impaired of alcohol or drugs may be eligible to get rehabilitation services for their problem rather than serving time in prison. The judge might order the individual receive rehabilitation, either alone or in addition to other consequences. Very first time offenders in particular tend to be given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they reap the benefits of it if it is an alternative. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done 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 rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in treatment have a better possibility of remaining out of the system following treatment.
