Criminal justice client rehabs are available like a far better option than prison time or significant fines for many who have been convicted of any type of drug or alcohol related crime. For instance, someone who has been in prison for driving under the influence of drugs or alcohol may qualify for rehabilitation services for his or her problem instead of serving time in prison. The judge might even order the individual receive rehab, either alone or along with other sentencing. First time offenders in particular in many cases are given the chance to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it is a possibility. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that take part in rehabilitation have a much better probability of remaining out of the system following treatment.
