Criminal justice client rehabs are available as a far better option than prison time or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. By way of example, someone who has been found guilty of driving drunk of alcohol or drugs may be eligible to get rehabilitation services for problem instead of serving time in jail. The judge could even order that the individual receive rehab, either alone or in addition to other sentencing. First-time offenders in particular are often given the chance to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it when it is an alternative. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out 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 rehabilitation. All indicators seem quite positive, and criminal justice clients that do experience rehab have a much better probability of remaining out of the judicial system following rehab.
