Criminal justice client rehabs can be considered like a significantly better option than jail time or heavy fines for many who have already been convicted of any kind of drug or alcohol related crime. For instance, somebody who has been in prison for driving under the influence of alcohol or drugs may qualify to obtain rehab services for his or her problem as an alternative to serving time in jail. The judge might even order that the individual receive treatment, either alone or together with other sentencing. First-time offenders in particular in many cases are given the ability to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended they reap the benefits of it when it is an alternative. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into treatment than punishment. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a better chance of remaining out of the system after rehabilitation.
