Criminal justice client rehabs can be considered like a far better option than jail time or significant fines for many who have been convicted of any type of drug or alcohol related crime. For example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to get treatment services for his or her problem as opposed to serving time in prison. The judge might order the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders in particular are often given the ability to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it when it is a choice. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into rehab than punishment. Much research has been done to discover how effective this process 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 quite positive, and criminal justice clients who take part in rehab have better possibility of remaining out of the judicial system after rehab.
