Criminal justice client rehabs can be considered as being a significantly better option than time in jail or heavy fines for individuals who have been convicted of any kind of drug or alcohol related crime. For example, someone who has been in prison for driving under the influence of drugs or alcohol may qualify to obtain rehab services for their problem as opposed to serving time in prison. The judge might even order the individual receive rehabilitation, either alone or in addition to other sentencing. Very first time offenders in particular tend to be given the ability to go with a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been completed to find out 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 quite positive, and criminal justice clients that take part in rehab have a better potential for remaining out of the system after treatment.
